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
