# AdjustPaneSize

*Since: 20201031-154415-9614e117*

`AdjustPaneSize` manipulates the size of the active pane, allowing the
size to be adjusted by an integer amount in a specific direction.

If the pane is on the right hand side of a split and you adjust the size
left by 1 then the split grows larger by 1 cell by expanding its size to
the left.  The pane to its left is reduced in size by 1 cell to accommodate
the growth.   If you were to adjust this same right hand side right by 1 cell,
then the pane will shrink by 1 cell and move the split 1 cell to the right.

Here's a sample configuration that uses `CTRL-A H` to increase the size
of the active pane by 5 cells in the left direction.  The other `vi` style
motion keys are used to adjust the size in their conventional directions,
respectively.

```lua
local wezterm = require 'wezterm';

return {
  leader = { key="a", mods="CTRL" },
  keys = {
    { key = "H", mods = "LEADER", action=wezterm.action{AdjustPaneSize={"Left", 5}}},
    { key = "J", mods = "LEADER", action=wezterm.action{AdjustPaneSize={"Down", 5}}},
    { key = "K", mods = "LEADER", action=wezterm.action{AdjustPaneSize={"Up", 5}}},
    { key = "L", mods = "LEADER", action=wezterm.action{AdjustPaneSize={"Right", 5}}},
 }
}
```
