I did the same thing on my Ergodox with QMK, only with emacs/readline bindings. control-M for enter, control-A for beginning of line, control-E for end of line, control-N for next line, control-H for backspace etc... It makes using those clunky web edit boxes (such as the one I'm typing this into right now) somewhat bearable. Getting a fancy ergonomic programmable keyboards is one of the best decisions I've made over the past few years. It's so much more comfortable in the long run. I'm also a big fan of "space cadet shift", which makes left and right shift input ( and ) when pressed on their own. I also have a dual-function caps lock: when pressed on its own it's Escape, when chorded with an other key it's control. You can do that in software with xcape for those who want to give it a try: xcape -t 500 -e 'Shift_L=parenleft;Shift_R=parenright;Control_L=Escape' You'll have to swap left control and caps lock using xmodmap or setxkbmap as well. And for those who are curious to see what a QMK config looks like, it's fairly straightforward (this one is a WIP, there are a few problems with it, but it gives you an idea): https://github.com/simias/qmk_firmware/blob/372b71ca90df01b51c151d34a1e7266444a12497/keyboards/moonlander/keymaps/simias/keymap.c https://github.com/simias/qmk_firmware/blob/372b71ca90df01b5... That's of course assuming that your board is already supported, adding support for a new board is a bit trickier and requires some embedded C know-how.
