To map the Microsoft Natural Ergonomic 4000 Keyboard's right and left arrow pad
(between your thumbs on the keyboard), ...
This is deprecated both because the link below doesn't exist and the keyboard
is no longer available.
Specifically, how to remap the slider. I found this post about activating the
between-keys zoom slider and using for scrolling instead of zooming:
The first (and easiest) solution worked for me on Linux Mint 13 (Ubuntu). For
the second solution, which I didn't implement, but which I had already seen
elsewhere, I had to go all the way to event7 before getting a reaction from the
Go to Keyboard preferences (System -> Preferences -> Keyboard or
to the Unity gear icon and look for Keyboard) and select a
Compose key by clicking the Layout tab, and then
Options, then Compose key position. Pick a key; in the image
below, I've chosen to use the left-side Windows key.

The key you choose enables you to compose an accented character at the keyboard.
To accomplish this, hold the key down and then type the accent character, see

needs are infrequent (usually only for testing software) and the trouble is
Still another method: For Russian, I'm a lot more competent, but not on the

Videos on fixing the infamous double-click problem that plagues Logitech mice:
There are quite a number of videos on this topic. I have had mice go bad this

upgrades. (When you're a hammer, everything looks like a nail, right?)
Advice: don't remove the white, plastic switch pad from the black case. Tape it
