Shortcut to previous item, eg. (CTRL)+V+(space)

[MarcoWagner]

Is your feature request related to a problem? Please describe.
I used Clip-X before and I got used to switching between the last 2 clipboards via keyboard shortcuts

Describe the solution you'd like
A keyboard shortcut that is reachable with one hand to switch between the actual and previous item.

Describe alternatives you've considered
Using autohotkey to map (CTRL)+(space) to (CTRL)+V+(down). But AHK seems to mess things up
