I recently had help fixing M-left
and so forth here: emacs in terminal meta arrow keybindings, but am unable to fix Shift-up
using a similar solution.
Just to add more information about the solution: https://github.com/arthurnn/dotfiles/blob/8d56f2419da9a4cb654d8941f379d6d5783bdb90/.emacs.d/init.d/setup-bindings.el#L3-L10 this should fix all the cases including emacsclient. The last line is responsible for fixing the Shift-up when using emacsclient.
