+Uzbl will read commands via standard input, named fifo pipe (if `fifo_dir` is set) and IPC socket (when `socket_dir` is set).
+For convenience, uzbl can also be instructed to read commands from a file on startup by using the `-c` option. Indeed, the config file is nothing more than a list of commands.
+
+Each command starts with the name of the command, which must be the first thing on a line; preceding whitespace is not allowed.
+A command is terminated by a newline. Empty lines and lines that start with the hash sign are ignored by the parser. Command names are always written in lowercase.
+
+The following commands are recognized:
+
+* `set <key> = <value>`
+ - used for changing variables on the fly
+ - the changes are effective immediately; for example, setting the variable `uri` will make uzbl start loading, and changing `status_format` will make the status bar react immediately
+ - if you want to unset a string, use `set` with one space after the equals sign
+* `print @<key>`
+ - use this to print the value of a variable.
+* `bind <string> = <command>`
+ - sets the character sequence `<string>` to invoke `<command>` when typed interactively in uzbl
+ - there are a few tricks you can do:
+ * `<string>` ends with an underscore: the command will only be invoked after pressing return/enter. If the user enters text where `<string>` has the underscore, `%s` in the `<command>` string will be replaced by this text. (optional)
+ * `<string>` ends with an asterisk: similar behavior as with an underscore, but also makes the binding incremental (i.e. the command will be invoked on every keystroke).
+ * `<string>` ends on a different character: you need to type the full string, which will trigger the command immediately, without pressing enter/return.
+ - examples:
+ * `bind o _ = uri %s`
+ - uzbl will load the url when you type: 'o <url><enter>'
+ * `bind /* = search %s`
+ - a search command which is called on every character typed after the slash, letting you see the search narrow down while typing.
+ - Hitting return, enter or esc will terminate the search.
+ * `bind ZZ = exit`
+ - When you type `ZZ` and nothing else, the exit command will be triggered immediately.
+
+* `back`
+* `forward`
+* `scroll_vert <amount>`
+* `scroll_horz <amount>`
+ - amount is given in pixels(?) or as a percentage of the size of the view
+ - set amount to 100% to scroll a whole page
+* `scroll_begin`
+* `scroll_end`
+* `reload`
+* `reload_ign_cache`
+* `stop`
+* `zoom_in`
+* `zoom_out`
+* `uri <address>`
+* `js <body>`
+ - execute the javascript in `<body>`
+ - remember that the commands must not contain line breaks
+* `script <file>`
+ - execute the javascript in `<file>`
+* `toggle_status`
+* `spawn <executable> <additonal args>`
+ - runs a command; see EXTERNAL SCRIPTS for details
+ - PATH is searched so giving the full path to commands is not neccessary
+ - note that the arguments as specified in "EXTERNAL SCRIPTS" are appended at the end, so the argument numbers will be higher.
+* `sh <command>`
+ - runs a shell command by expanding `%s` in the `shell_cmd` variable with the specified command; primarily useful as a shortcut for `spawn sh -c <body>`
+ - note that the arguments as specified in "EXTERNAL SCRIPTS" are appended at the end, so the argument numbers will be higher.
+* `sync_spawn <executable> <additional args>`
+* `sync_sh <command>`
+ - these are synchronous variants of `spawn` and `sh`, which means uzbl will wait for them to return
+ - you should only need to use these manually if you want to use a chain command in a handler that wants output from the command it runs
+* `exit`
+* `search <string>`
+* `search_reverse <string>`
+ - search with no string will search for the next/previous occurrence of the string previously searched for
+* `toggle_insert_mode <optional state>`
+ - if the optional state is 0, disable insert mode. If 1, enable insert mode.
+* `dump_config`
+ - dumps your current config (which may have been changed at runtime) to stdout, in a format you can use to pipe into uzbl again (or use as config file)
+* `keycmd <string>`
+* `keycmd_nl <string>`
+ - keycmd sets the interactive command buffer to `<string>`. If the given string is a valid binding, it will execute. `Keycmd_nl` is like `keycmd`, but it also emulates a press of return, causing bindings with a parameter to execute. For example, `keycmd_nl o google.com` would load the said url if you have a binding like `bind o _ = uri %s`.
+* `keycmd_bs`
+ - erase (backspace) one character from the command buffer
+* `chain <command> <command> ..`
+ - use for chaining multiple commands
+ - remember to quote the commands; one command must come as one parameter
+ - if you use `chain` with a handler script which must return some output (such as a cookie handler -- uzbl will wait for and use its output), use sync_spawn or sync_sh instead of spawn or sh in the command that should give the output
+
+### JAVASCRIPT HELPER OBJECT
+
+Javascript code run from uzbl is given a special object in the global namespace which gives special privileges to these scripts. This object is called `Uzbl`, and it is added and removed before and after the script execution so that it is hidden to web javascripts (There is no race condition, since all the javascript code runs in a single thread)
+
+Currently, the `Uzbl` object provides only one function:
+
+* `Uzbl.run( <command> )`
+ - command is any uzbl command as defined above
+ - return value: a string, either empty or containing the output of the command. Very few commands return their output currently, including js, script, and print.
+ - Examples:
+ * `Uzbl.run("spawn insert_bookmark.sh")`
+ * `uri = Uzbl.run("print @uri")` (see variable expansion below)
+
+### JAVASCRIPT SECURITY
+
+Since defined variables and functions are set in the global namespace (`window` object) as default, it is recommended to wrap your scripts like this:
+
+ (function(Uzbl) {
+ ...
+ })(Uzbl);
+
+This way, everything is kept private. It also turns Uzbl into a local variable, which can be accessed from callback functions defined inside. However for some situations, isolating everything isn't an option, for example, with binds. You can define them directly in the script body, and use `var Uzbl = window.Uzbl;` to make the Uzbl variable local, as in the following example:
+
+ function f() {
+ var Uzbl = window.Uzbl;
+ Uzbl.run(...);
+ setTimeout(function() {
+ Uzbl.run(...);
+ }, 500);
+ }
+
+Copying the Uzbl object and creating public functions should be taken with care to avoid creating security holes. Keep in mind that the "f" function above would be defined in the `window` object, and as such any javascript in the current page can call it.
+
+### VARIABLE EXPANSION AND COMMAND/JAVA SCRIPT SUBSTITUTION
+
+Variable expansion works pretty much as known from shell interpreters (sh, bash, etc.). This means you can
+construct strings with uzbl variables in them and have uzbl replace the variable name with its contents.
+
+In order to let uzbl know what to expand you'll need to prepend @ to the variable name:
+
+ print The variable \@show_status contains @show_status
+
+The above example demonstrates two things:
+
+ * '\' is treated as escape character and will use the character immediatelly following it literallily
+ this means '\@show_status' will not expand to the variable content but be rather printed as
+ '@show_status'
+
+ * prepending the variable with '@' will expand to its contents
+
+ * like in the shell you can use @{uzbl_var} to denote the beginning/end of the variable name in
+ cases where it is not obvious what belongs to the name and what not.
+ E.g.: print @{show_status}foobar
+
+
+Command substitution will launch any commands and substitute the call with the return value of the command.
+
+Uzbl will substitute any commands enclosed within @( )@:
+
+ print Command substitution: @(uname -a)@
+
+You can access any uzbl variable from within a command substitution:
+
+ print @(echo -n 'Accessing the show_status var from an external script, value: @show_status')@
+
+
+Java script substitution works in the exact same way as command substitution but you will need to enclose
+the java script in @< >@.
+
+ print The currently viewed document contains @<document.links.length>@ links
+
+Variable expansion also works within a java script substitution.
+
+
+NOTE: If you need to use literal @ or \ characters you will need to escape them:
+
+ print At sign: \@ and backslash: \\
+
