MoveTabRelative

Move the current tab relative to its peers. The argument specifies an offset. eg: -1 moves the tab to the left of the current tab, while 1 moves the tab to the right.

local wezterm = require 'wezterm'
local act = wezterm.act

return {
  keys = {
    {key="{", mods="SHIFT|ALT", action=act.MoveTabRelative(-1)},
    {key="}", mods="SHIFT|ALT", action=act.MoveTabRelative(1)},
  }
}
