local keymap = {
  KEY_LEFT_CTRL = '0x80',
  KEY_TAB = '0xB3',
  KEY_RETURN = '0xB0',
  -- ... full table in macro-demo.lua
}

function this:get_keymap(k)
  return tonumber(keymap[k])
end

function this:move(x, y, z)
  -- splits moves into 100px steps for the HID protocol
end

function this:alt_tab()
  self:call('kpress ' .. self:get_keymap('KEY_LEFT_ALT'))
  self:call('kwrite ' .. self:get_keymap('KEY_TAB'))
  self:call('krelease ' .. self:get_keymap('KEY_LEFT_ALT'))
end
