Implement modes. Modes allow you to use different keybindings and switch between them.

Browse Source 
For example, you can create a mode which will let you resize windows
with some easy to use keys. So, instead of binding a combination
of your homerow and modifiers to resize, like this:

	bind Mod4+44 resize right +10
	bind Mod4+45 resize right -10
	...

You can instead define a new mode:

	mode "resize" {
		bind 44 resize right +10
		bind 45 resize right -10
		...
		bind 36 mode default
	}

	bindsym Mod4+r mode resize

So, if you press Mod4+r now, your keybindings will be set to the ones
defined in your resize mode above. You can then use your homerow
(without any other modifier) to resize the current column/row and
press enter to go back to the default mode when you are done.

Note that using this option requires you to enable the new lexer/parser
by passing the -l flag to i3 when starting.
