I tried a number of clipboard managers looking for the best combination of:
-Copy formatted text, paste as plain text (as two steps: 1.copy & 2.paste, no in-between step)
-Paste from clipboard history (as either formatted text or plain text)
-Small memory footprint, minimal performance drag
I liked ArsClip on the first two fronts, but not on the 3rd. I eventually turned to the clipboard management built into my favorite multi-purpose app (launcher, sys info, window management, hotkey manager, sticky notes, etc):
Windows PowerPro.
I then decided that it would be nice to add the ability to change text case easily. PowerPro has functions for converting text to upper, lower, title, sentence case and more.
Two other tools that can handle this sort of thing are
AutoIt and
AutoHotKey.
