aka "typing break" drwright - Typing monitor to force typing breaks
It's a program that forces you to take regular breaks to prevent RSI (Repetitive Strain Injury). It's similar to workrave. It can be found in GNOME control center as "typing break".
It used to be part of GNOME 2's main core, but is now packaged separately.
- You can specify the work interval (how much time you want to work between breaks) and a break interval (how long your break will be).
- It also allows postponing of breaks.
- There is an option to lock the screen in case you want to step out indefinetely (v3.2.3).
