For example, if you have a binding like "o _" that opens an URL, then you could create a binding `O` that spawns a script which will set the command buffer to "o current-uri-here", letting you enter relative URLs easily.
(See sample config)
+### ACTIONS
+Actions are invoked via bindings and by the ACT command. Most actions are self-explanatory, though a few need to be clarified. A list of action follows:
+
+ * `back`
+ * `forward`
+ * `scroll_vert <amount>`
+ * `scroll_horiz <amount>`
+ * `scroll_begin`
+ * `scroll_end`
+ * `reload`
+ * `reload_ign_cache`
+ * `stop`
+ * `zoom_in`
+ * `zoom_out`
+ * `uri <address>`
+ * `script <body>`
+ - execute the javascript in `<body>`
+ - remember that the commands, and thus actions, must not contain line breaks
+ * `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
+ * `sh <script body>`
+ - runs a command by expanding `%s` in shell_cmd with the script body; primarily useful as a shortcut for `spawn sh -c <body>`
+ * `exit`
+ * `search <string>`
+ * `search_reverse <string>`
+ * `insert_mode`
+ * `runcmd`
+ - can be used for running a command such as SET or BIND
