This is about as simple as AHK can be, but I thought I would share it as I find it quite useful. This script lets you accumulate multiple chunks of text on the clipboard and then paste them all at the end. It can be used, for example, when a client wants you to translate specific sections of text in a document and you want to quickly collect just those parts and then paste them into a blank document. Much simpler and easier than copying and pasting multiple items one at a time.
(Just use control + shift + c / v to use this script)
multiclip := multiclip . "`n" . clipboard
clipboard := multiclip
