Atom should have the ability to quickly reopen a closed tab using the cmd+shift+t keyboard shortcut.
cmd+shift+t
This already exists? CMD+SHIFT+P and type “reopen”. It is Pane: Reopen closed item. It has the default shortcut of CMD+SHIFT+T, so if it’s not working, you either didn’t close anything or are overriding it with something else.
CMD+SHIFT+P
CMD+SHIFT+T
Add this to your keymap.cson file to add the shortcut if it’s not already working.
'body': 'cmd-shift-t': 'pane:reopen-closed-item'
For me it turned out I needed:
'atom-workspace': 'ctrl-shift-t': 'pane:reopen-closed-item'
A package I installed was overriding the default behavior.
