Having navigational keys on the home row is something every software developer should use (but almost no one does). Unlike Vim-style keybindings it just works everywhere.

Personally I am using an unused key on my keyboard (layout) as modifier to access them. My particular mapping is based on the Neo Layout [0]. Basically FPS-style WASD but shifted by one key to the right.

As tool to change keyboard layout I use Interception Tools [1] and a personal C program. The advantage of interception tools is that it works everywhere (even outside a desktop environment).
