MoveTab

Move the tab so that it has the index specified by the argument. eg: 0 moves the tab to be leftmost, while 1 moves the tab so that it is second tab from the left, and so on.

local wezterm = require 'wezterm'

local mykeys = {}
for i = 1, 8 do
  -- CTRL+ALT + number to move to that position
  table.insert(mykeys, {
    key = tostring(i),
    mods = 'CTRL|ALT',
    action = wezterm.action.MoveTab(i - 1),
  })
end

return {
  keys = mykeys,
}
