# Keymapping philosophy:
# When I feel it's appropriate, I try to borrow existing KBDs from OSX or
# Windows. For example, I use Ctrl+Alt+Del to start the screen lock, since this
# is a really well-known KBD. One notable difference is that when I'm borrowing
# OSX KBDs, I prefer using Alt instead of Super since the keyboard that I'm
# using has the Alt key in the same location as the Super key on my mac
# keyboard. I could rebind this, and I just may. But for now, that's worth
# pointing out.
# The reason behind borrowing from Windows and OSX is that some of these
# keybindings are hardwired into my muscle memory. I also tend to work between
# Linux and OSX quite often. Since OSX is much more difficult to remap KBDs
# than it is in Linux, I prefer to support the OSX KBDs to reduce the number of
# KBDs my feeble memory needs to store.
