"""
|

|
|
This plugin exports four functions - up, down, left and right - that when called will
|
||
|
|
move window focus to the first window in that general direction. Focussing is based
|
||
|
|
entirely on position and geometry, so is independent of screens, layouts and whether
|
||
|
|
windows are floating or tiled. It can also move focus to and from empty screens.
|
||
|
|
|
||
|
|
Example usage:
|
||
|
|
|
||
|
|
import traverse
|
||
|
|
|
||
|
|
keys.extend([
|
||
|
|
Key([mod], 'k', lazy.function(traverse.up)),
|
||
|
|
Key([mod], 'j', lazy.function(traverse.down)),
|
||
|
|
Key([mod], 'h', lazy.function(traverse.left)),
|
||
|
|
Key([mod], 'l', lazy.function(traverse.right)),
|
||
|
|
])
