I've used Autohotkey (Windows) to remap my capslock to select the word my cursor is currently in. Essentially pressing ctrl+left, then ctrl+shift+right. I too have become so use to this that using other people's keyboards is frustrating. I've taken this a couple steps further, shift+capslock selects the current line and ctrl+capslock activates Sublime's multicursor feature.

This won't work in everything, will it? What about if your cursor is at the beginning of a word? Not to mention that different editors stop in different places with ctrl+arrows. Many editors have a key combo for select word already. In Visual Studio it's ctrl-w.

I've been using it for about 1.5 years, and it's been mostly consistent between applications; Notepad being the only one I've noticed with odd characters it includes in the ctrl+arrow movements. I really like the approach using Autohotkey because it becomes universal on my system, so capslock can select words in chrome, IM apps, etc. I don't have to worry that the app supports that feature.
