Make it easy to pop into group by sort mode by attaching the G key to it.
fixed branch and trunk
Scott, there is no shortcut to leave this sort mode. Pressing 'G' again should switch into unthreaded sort mode. By the way we could also need a shortcut for threaded mode. So we could switch between all three sort modes.
After discussing this feature to have a shortcut for switching into a special sort mode we finally came to the result that it's not good. How often do you switch between different modes? That's rarely. We shouldn't waste a one key shortcut for that. Scott, what was your reason to add this shortcut especially for that sort mode?
no it shouldn't pop you back out
This "fix" causes substantial breakage for many other people (bug 199019, bug 275871, bug 309010, et al).
