I'm migrating to a shiny new laptop (yay) unfortunately I've manually set up my iTerm to match the old machine, but something is not right (not yay).

I'm experiencing

• using xterm-256color doesn't give the full colour set for say, vim.
• applications like vim dont clear out of the scrollback when exited.
• my home and end keys are completely broken and I cant seem to google up a solution
• my backspace key doesn't delete backwards, it adds a 'space' and prevents further input until ^C

Here is my .zshrc, my .profile. I dont have an .inputrc

Here are my keyboard settings for iTerm2:

I'm fairly sure i've broken something between $TERM, iTerm2's keyboard settings and my .zshrc, but I'm simply not competent enough to debug it. As far as I can tell, my settings are identical to my old laptop, which works.
