Description Andrew Obuchowicz CLA 2020-04-06 10:57:47 EDT 
As an Emacs user, it's bothered me since I started using Eclipse that the Emacs key bindings don't have the correct key binding for undo/redo.

By default, undo in Emacs is invoked with CTRL + /, see https://www.gnu.org/software/emacs/manual/html_node/emacs/Undo.html

A popular package for Emacs is undo-tree.el, which binds redo to CTRL + ?, see http://www.dr-qubit.org/undo-tree/undo-tree.el under Quick Start.

IMO, at the very least, a keybinding for the undo command in the Emacs keybindings should be CTRL + / as this is the default. Ideally, CTRL + ? should redo. 

I'm willing to submit a patch for this, as it gets tedious to re-input these keybindings when creating a fresh workspace. Also, this is important to ease the adoption of Eclipse from Emacs users.

I might have targeted the wrong component with this bug, if so, someone is free to retarget it to the correct component. 
Thanks.
