Arrow left and right key turn into enter and type C or D character

but when I commented at these settings, my arrow keys work fine again

"imap (PearTreeBackspace)
"imap (PearTreeExpand)
"imap (PearTreeFinishExpansion)

This is normally caused by mapping the <Esc> key to something in insert mode. While Pear Tree does map <Esc> by default, it uses a workaround that is supposed to prevent this issue.

• What Vim are you using (terminal, graphical, Neovim, etc.) and what version number?
• Have you remapped <Esc> in your config?

I'm closing this issue since it seems to stem from remapping <Esc>. Pear Tree maps it by default, but if you must remap it in your own config, you could take a look at the workaround used to prevent arrow keys from breaking.
