Advanced key mappings in linux

I am using manjaro i3 and am looking into revamping some of the key mappings I have made. Currently I am using xcape, xmodmap, and setxkbmap commands to remap the following keys: 1. caps to contol when held, escape when pressed 2. swap semi colon and colon I have done this with this setup script: setxkbmap -option 'caps:ctrl_modifier' xcape -e 'Caps_Lock=Escape' xmodmap -e "keycode 47 = colon semicolon" I wanted to ask for some help or advice for the additional changes I am looking to make since I have already broken my key mappings and had to reinstall my os to get back to square one when playing around with the print screen remapping listed below. The changes I am looking to make are the following: 1. print screen --> disable or use as another super key 2. left alt --> mode_switch key 3. escape key --> tilde and backtick 4. original tild and back tick --> backspace 5. backspace --> delete 6. disable home, end, insert, delete keys and map them to run some script 7. mode_switch + h, j, k, l --> additional arrow keys 8. mode_switch + backspace --> home 9. mode_switch + delete --> end What tools should I be using to acccomplish these remappings? Also, if anyone has some similar examples they have used in the past that would be really helpful too! Thanks in advance for any help.
