|
# Usage: |
|
# To enable key bindings, add the following to zshrc, and replace 'map' with |
|
# 'emacs' or 'vi. |
|
# |
|
# zstyle ':omz:module:editor' keymap 'map' |
|
# |
|
# To enable the auto conversion of .... to ../.., add the following to zshrc. |
|
# |
|
# zstyle ':omz:module:editor' dot-expansion 'yes' |
|
# |
|
# To indicate when the editor is in the primary keymap (emacs or viins), add |
|
# the following to your theme prompt setup function. |
|
# |
|
# zstyle ':omz:module:editor:keymap' primary '>>>' |
|
# |
|
# To indicate when the editor is in the primary keymap (emacs or viins) insert |
|
# mode, add the following to your theme prompt setup function. |
|
# |
|
# zstyle ':omz:module:editor:keymap:primary' insert 'I' |
|
# |
|
# To indicate when the editor is in the primary keymap (emacs or viins) overwrite |
|
# mode, add the following to your theme prompt setup function. |
|
# |
|
# zstyle ':omz:module:editor:keymap:primary' overwrite 'O' |
|
# |
|
# To indicate when the editor is in the alternate keymap (vicmd), add the following |
|
# to your theme prompt setup function. |
|
# |
|
# zstyle ':omz:module:editor:keymap' alternate '<<<' |
