PureText is a simple little tool that could save me hours of my life. I searched for it today before I began to write such a tool for the third time. Here's a summary by the author (the guy who writes DependencyWalker):
PureText is basically equivalent to opening Notepad, doing a PASTE, followed by a SELECT-ALL, and then a COPY. The benefit of PureText is performing all these actions with a single Hot-Key and having the result pasted into the current window automatically.
Basically, this describes what I do about 5-30 times a day. I grab something formatted and want to paste it into another document or email, but I rarely want to keep the formatting. Before this tool, I copied the text to the clipboard, then I hit this arcane sequence of keys: WindowsKey-N (my Notepad hotkey), Ctrl-V, Ctrl-A, Ctrl-C, Alt-F, x. Now that I've bound this tool to WindowsKey-Q, I've shortened 6 keystrokes (with slight delays) to 1 immediate keystroke.
It may seem silly, but it's worth it for me.
