SAVE SELECTION
|
|
Simple shortcuts to have multiple selection bufers
|
|
|
|
|
|
USAGE
|
|
* require this file from your main lua config file:
|
|
* go to configuration => preferences => lua
|
|
* set the shortcuts you want to use
|
|
|
|
This plugin will provide shortcuts to save to and restore from up to five temporary buffers
|
|
|
|
This plugin also provides a shortcut to swap the current selection with a quick-swap buffer
|
|
|
|
The variable "buffer_count" controls the number of selection buffers,
|
|
increase it if you need more temporary selection buffers
