I know I can do control+a but I want command+left. I'm using the fish shell.
I tried creating an apple script to call control+a when I hit command+left but that caused it to call command+control+a which didn't work.
I couldn't figure out how to change command+fn+delete to C-k.
There's also a predefined setting in terminal.xml, but it only works with the left command, and it includes other remappings that aren't really needed anymore.
You can make ⌥⌦ delete a word forward by adding this to ~/.inputrc:
