Keybindings

⌨ How to bind "simultaneous key combinations" (as in key-chord.el or vim-arpeggio)?

# blerc

# Example 1: Bind j&k with timeout of 40 msec
ble-bind -m vi_imap -f 'j k' 'vi_imap/normal-mode'
ble-bind -m vi_imap -f 'k j' 'vi_imap/normal-mode'
ble-bind -m vi_imap -T j 40
ble-bind -m vi_imap -T k 40

# Example 2: Use library "vim-arpeggio.sh"
source "$_ble_base/lib/vim-arpeggio.sh"
bleopt vim_arpeggio_timeoutlen=40
ble/lib/vim-arpeggio.sh/bind -m vi_imap -f jk vi_imap/normal-mode

⌨ How to edit a command line in vim (like v in default Bash vi-command map)?

# blerc

# Example 1: Bind "C-x C-v" for Emacs mode
VISUAL='vim -X'
ble-bind -m emacs -f 'C-x C-v' 'edit-and-execute-command'

# Example 2: Bind "C-x C-v" for Vim mode
VISUAL='vim -X'
ble-bind -m vi_imap -f 'C-x C-v' 'edit-and-execute-command'
ble-bind -m vi_nmap -f 'C-x C-v' 'vi-command/edit-and-execute-command'

⌨ M-right does not work in my terminal.

This is related to your setting of the Meta key in the terminal. There are historically two different roles for Meta key in terminals:

Meta character: One is to send a meta character (such as alphabets with accents, etc. depending on your settings of language, e.g., Á with "Meta + A"),
Meta modifier: The other is to send an escape sequence which represents a modifier "Meta" (M- in Emacs notation).

Depending on your terminal and the preferred behavior, the appropriate setting could vary. Below is the setting for iTerm2:

Option 1 (Always Meta modifier): If you want to always send M-something with all the keys combined with Meta key, you can select "Esc+" for "Left/Right ⌥ Key" as in the image in this answer.
Option 2 (Meta modifier only for function keys): This is the setting for the case you want to normally send meta characters for "Meta + character (such as alphabets/numbers/delimiters)", and only send escape sequences for "Meta + function (such as left/up/home/pagedown/delete, etc.)". It seems "Natural Text Editing" in iTerm2 does that, so you can try to enable "Natural Text Editing". In this case you need to turn the "Left/Right ⌥ Key" settings back to "Normal". If this setting does not work, please use the following Option 3.
Option 3 (Meta modifier for specified keys): If you want to send meta characters by default and want to one-by-one specify special key combinations that should send meta modifier, you can set a escape sequence for each key combination. Specifically for M-right, you can follow this answer. The answer describes the setting to let Meta + left/right send M-b/M-f to terminal applications. In this case please set the "Left/Right ⌥ Key" setting to "Normal" or "Meta".
Option 4 (Meta character for "Left ⌥" and Meta modifier for "Right ⌥"): You can also assign different roles to "Left/Right ⌥". For example, if you want to send meta characters for "Left ⌥" and meta modifiers for "Right ⌥", please set "Left ⌥ Key" to be "Meta" and "Right ⌥ Key" to "Esc+".

⌨ How to use special key combinations such as S-RET, etc?

If you use the terminal with the feature called modifyOtherKeys, you can use these key combinations by default. If your terminal doesn't support modifyOtherKeys but can be configured to send specified escape sequences, please set the following escape sequences for the key combinations that you would like to use.

Key combination	Escape sequence	Key combination	Escape sequence
`S-RET`	`ESC [ 1 3 ; 2 u`	`C-0`	`ESC [ 4 8 ; 5 u`
`C-RET`	`ESC [ 1 3 ; 5 u`	`C-1`	`ESC [ 4 9 ; 5 u`
`C-S-RET`	`ESC [ 1 3 ; 6 u`	`C-2`	`ESC [ 5 0 ; 5 u`
`S-TAB`	`ESC [ 9 ; 2 u`	`C-3`	`ESC [ 5 1 ; 5 u`
`C-TAB`	`ESC [ 9 ; 5 u`	`C-4`	`ESC [ 5 2 ; 5 u`
`C-S-TAB`	`ESC [ 9 ; 6 u`	`C-5`	`ESC [ 5 3 ; 5 u`
`S-SP`	`ESC [ 3 2 ; 2 u`	`C-6`	`ESC [ 5 4 ; 5 u`
`C-S-SP`	`ESC [ 3 2 ; 6 u`	`C-7`	`ESC [ 5 5 ; 5 u`
`S-BS`	`ESC [ 8 ; 2 u`	`C-8`	`ESC [ 5 6 ; 5 u`
`C-S-BS`	`ESC [ 8 ; 6 u`	`C-9`	`ESC [ 5 7 ; 5 u`

For the detailed description, please see this section in the manual.

The terminals supporting modifyOtherKeys include xterm, mintty, iTerm2, foot, and zutty.

# For vim editing mode

⌨ How to run multiple widgets with a single key sequence?

You can define your own widget by creating a function of the name ble/widget/YOUR_WIDGET_NAME and calls multiple widgets there as illustrated in the following example. It is highly recommended to prefix the widget name with YOUR_NAME/, my/, blerc/, dotfiles/, etc. in order not to conflict with the names of the existing standard widgets.

# Example of calling multiple widgets with the key C-t
function ble/widget/my/example1 {
  ble/widget/beginning-of-logical-line
  ble/widget/insert-string 'echo $('
  ble/widget/end-of-logical-line
  ble/widget/insert-string ')'
}
ble-bind -f C-t my/example1
