/*
BB Key Bindings
User-defined key bindings go in config.h, which is created by running `make`
(config.def.h is for keeping the defaults around, just in case)
The basic structure is:
<list of keys to bind>
<program to run>
<description> (for the help menu)
<flags> (whether to run in a full terminal window or silently, etc.)
When the scripts are run, the following values are provided as environment variables:
$@ (the list of arguments): the full paths of the selected files
$BBCURSOR: the full name of the file under the cursor
$BB_DEPTH: the number of `bb` instances deep (in case you want to run a
shell and have that shell print something special in the prompt)
$BBCMD: a file to which `bb` commands can be written (used internally)
In order to modify bb's internal state, you can call `bb +cmd`, where "cmd"
is one of the following commands (or a unique prefix of one):
.:[01] Whether to show "." in each directory
..:[01] Whether to show ".." in each directory
cd:<path> Navigate to <path>
columns:<columns> Change which columns are visible, and in what order
deselect:<filename> Deselect <filename>
dotfiles:[01] Whether dotfiles are visible
goto:<filename> Move the cursor to <filename> (changing directory if needed)
interleave:[01] Whether or not directories should be interleaved with files in the display
jump:<key> Jump to the mark associated with <key>
mark:<key>[=<path>] Associate <key> with <path> (or current dir, if blank)
move:<num*> Move the cursor a numeric amount
quit Quit bb
refresh Refresh the file listing
scroll:<num*> Scroll the view a numeric amount
select:<filename> Select <filename>
sort:([+-]method)+ List of sortings (if equal on one, move to the next)
spread:<num*> Spread the selection state at the cursor
toggle:<filename> Toggle the selection status of <filename>
Internally, bb will write the commands (NUL terminated) to $BBCMD, if
$BBCMD is set, and read the file when file browsing resumes. These commands
can also be passed to bb at startup, and will run immediately.
E.g. `bb +col:n +sort:r .` will launch `bb` only showing the name column, randomly sorted.
*Note: for numeric-based commands (like scroll), the number can be either
an absolute value or a relative value (starting with '+' or '-'), and/or
a percent (ending with '%'). Scrolling and moving, '%' means percent of
screen height, and '%n' means percent of number of files (e.g. +50% means
half a screen height down, and 100%n means the last file)
