Bad Keyboard Advice from Programers
Symbol for the Menu Key
Unicode joy. Found a appropriate symbol to represent the menu key. For example, ▤ Menu.
So, now i have: Shift, ⌘ command, ❖ Window, ▤ Menu, Return, Enter, ⌥ option, ⌫ Backspace, ⌦ Delete, Tab.

Discovered this keyboard “ThinkPad USB Keyboard with TrackPoint” ThinkPad keyboard
It's a external USB keyboard, with embedded Pointing Stick (a red button between G and H). Compact, laptop style shallow keys.
I don't recommend it. Because laptop style keyboard is the fastest way to get RSI. If you are going to get a external keyboard, get a full-sized one.
My recommendations are:
- If you want split keyboard, see: How to Chose Ergonomic Keyboards
- If you want straight keyboard, try Mechanical Keyboard Reviews ⌨
All these have mechanical keys. (but check the page for detail).
Some people like the ThinkPad's Pointing Stick. I didn't like it. Too slow.
