# ActivateTab

Activate the tab specified by the argument value. eg: `0` activates the
leftmost tab, while `1` activates the second tab from the left, and so on.

*since: 20200620-160318-e00b076c*

`ActivateTab` now accepts negative numbers; these wrap around from the start
of the tabs to the end, so `-1` references the right-most tab, `-2` the tab
to its left and so on.


```lua
local wezterm = require 'wezterm'
local act = wezterm.action

local mykeys = {}
for i = 1, 8 do
  -- CTRL+ALT + number to activate that tab
  table.insert(mykeys, {
    key = tostring(i),
    mods = 'CTRL|ALT',
    action = act.ActivateTab(i - 1),
  })
  -- F1 through F8 to activate that tab
  table.insert(mykeys, {
    key = 'F' .. tostring(i),
    action = act.ActivateTab(i - 1),
  })
end

return {
  keys = mykeys,
}
```
