Can I chain keystroke shortcuts?

Is there a way to build a keystroke macro by calling multiple functions from the Shortcut menu?

I want to enhance the VSE by automating an insert edit. So I must split (K cut) a strip on the VSE, then Select Strips to the right (an actual tool) and move them across to the right. Ideally by the duration of my clipboard copied insert item, but it could be an arbitrarily large value, followed by a snap to function after the paste insert.
