Textcorder for Mac

From Red Byte Software:

Textcorder is an advanced keystroke recording extension. Everyday all the text you have written is saved to a log file, for later recovery. This is very useful if your computer crashes a lot and/or you type a lot of text.The differences between this extension and most other keystroke recording applications is that Textcorder is optimized for text-editing. That means for example that it can record more than 32k of text and that it deletes if the user deletes a word in the text-editor he is using. Even installing and uninstalling Textcorder is very easy...
