Insert functionality for keyboard commands.

[gmellogomind]

The keyboard commands such as bot.enter(), bot.tab(), among others, have an option for the wait argument, where an integer value is passed to wait after the action is performed.

I would like to suggest a modification to insert this option to wait both before and after the action, something like wait_before and wait_after, which would assist in development instead of having to pass a bot.wait() before performing the action.
