### Description
|
||||
Stacker is a patch that allows moving around the stack more freely. With only
|
||||
one keybinding, quickly move, swap and jump around the window stack.
|
||||
|
||||
1. Focus any window of the stack with a single key binding.
|
||||
2. Swap the currently focused windows with any other window in the stack.
|
||||
3. Move the selected window in the stack with `relativeswap`.
|
||||
|
||||
This patch is heavily inspired by the original [stacker](https://dwm.suckless.org/patches/stacker/) dwm patch.
|
||||
|
||||
### Keybinding
|
||||
|
||||
- `MODKEY` + {`q`, `w`, `e`, `r`}: jump to the first, second, third and last
|
||||
window of the stack
|
||||
- `MODKEY` + `SHIFT` + {`Q`, `W`, `E`, `R`}: swap the selected with the first, second, third and last
|
||||
window of the stack
|
||||
- `MODKEY` + `SHIFT` + {`J`, `K`}: move the selected window up & down the stack
|
||||
|
||||
### Missing feature
|
||||
|
||||
Jumping to the last selected window is not yet implemented.
