I recently picked up a Logitech Wireless Combo Mk520 With Keyboard and Mouse to use full time with my Acer Chromebook when I'm using it in desktop computer mode.
When I am in this mode I usually use the setup with a SAMSUNG T24C550 monitor as the primary monitor and the Acer's laptop monitor as my 2nd monitor off to the right-hand side.
I like this setup because it enables wireless access to both the keyboard and the mouse using one USB port. Previously I had a dedicated wireless mouse and then a bluetooth keyboard. However the bluetooth keyboard wasn't completely full-size, would periodically drop off connectivity, and was better suited to short-term typing like like periodic emails responses on my Nexus 7.
The only draw back with the Mk520 is that the Function (F) keys are not ideally setup to match the icons on them.
The keyboard uses the basic standard keyboard layout on most Chromebooks. So ESC is ESC (Escape) and:
- F1: Go to the previous page in your browser history
- F2: Go to the next page in your browser history
- F3: Reload your current page.
- F4: Open your page in full-screen mode
- F5: Switch to your next window
- F6: Decrease screen brightness
- F7: Increase screen brightness
- F8: Mute
- F9: Decrease system volume
- F10: Increase system volume
At the very top of the keyboard is a media control area (3 keys): back, play/stop, forward. Those don't seem to work with videos. But the sound control area (3 keys): mute, decrease sound, and increase sound do work. And the WINDOWS button is a dedicated SEARCH button; the STAR button brings up the BOOKMARKS page list; and the CALCULATOR button goes into FULL SCREEN MODE.
Over all the keyboard feel when typing is very good, and I like the pressure the keys have. In addition, I like the ability to tilt up the keyboard and to have it stand-up at 90-degrees for using your desk area for writing if needed. I would recommend the keyboard if someone is looking for the same feature set.
