I have used a similar windows trick. I wanted to add to the default window system a place for my library of tools. Most are "portable" cmd apps from various sources (sysinternals, nirsoft). I put them all into a directory called ] in the root of a drive.

Because of some common layout of keyboards the \ and ] are near each other, or in reach of left and right pinkies I can type \]\ before the name of the tools. This means I don't even have add a dir to the path.

I am sure this violates someone sensibilities but it has saved time over the years as a consultant when I had to deal with a wonky machine and owner did not want permanent install of diagnostic tools.
