Please add it back. Reproducible: Always Steps to Reproduce: 1.Attempt to hit keyboard key "G" to group the emails. 2. 3. Actual Results: nothing happens Expected Results: toggle the grouped by sort feature.

I can confirm that the G shortcut is missing, very inconvenient. Please re-add asap.

The "G" single-key shortcut for "group by sort" was intentionally removed by Bug 275871 - View->Sort By->Grouped by Sort keyboard shortcut goes against interface guidelines (back out bug 263919) The main reasons cited were afasik: 1 usability problem: if hit accidentally, there is no easy way to get out of "grouped by sort" mode 2 consistency problem: single-letter shortcuts are basically reserved for message-related actions (as opposed to view changing) Both points are certainly arguable. To re-add the shortcut, you can install the Threadkey addon https://addons.mozilla.org/en-US/thunderbird/addon/threadkey/ which will add the following shortcuts: - T for threaded - U for unthreaded - G for grouped by sort In the long run, we may want an inbuilt solution for this, as requested by Bug 263571 - Improve mode switching between Threaded, Unthreaded, and Grouped By Sort (column headers, unthread pref, G keyboard shortcut).

As per comment 3, this is the expected behaviour, so marking it as WONTFIX.
