This hint is simple. There is a new freeware utility called ClipMenu. It's a multi-clipboard manager that you invoke using hotkeys. I have mine set to open on the Command+Control+C key. You can easily set up the option to invoke a paste as plain text using a hot key and mouse click in the preferences. It also supports snippet libraries, as well as a variety of data types on the clipboard. It's a Universal binary.
[crarko adds: It's another addition to the selection of clipboard managers. It looks like it has some useful features. I'll try it out as a complement to PTHPasteboard, which is what I've generally used. By the way, I don't think the submitter is the program's author.]
