Convenience Functions
|
||||
---------------------

||||
|
||||
### bindkey-all
|
||||
|
||||
Provides a function `bindkey-all` which can be useful for checking how all of the
|
||||
keys are bound. Normal `bindkey` command will only list the keys bound for one
|
||||
keymap, which is not as useful if you want to grep through the output. The
|
||||
keymap's names go to stderr so when you grep through bindkey-all's output you
|
||||
will still see the headings and can tell which keymap each binding goes to.
|
||||
|
||||
It will also pass through arguments so you can use bindkey-all to set bindings
|
||||
for all keymaps at once. If provided arguments it will *not* print out the
|
||||
names of each of the keymaps, and just run the command for each keymap.
