Maybe we better remove View Gallery / .uno:Gallery. Along with View > Sidebar toggling the sidebar with all tabs and View > Navigator showing an extra window (and the other options there) this command seems to be alien.

Stuart, what do you think?

Yes, the command resident on the View -> Gallery is somehow incorrect. Assigning the .uno:Gallery to keyboard shortcut it behaves as I'd expect--refocusing an open (collapsed or expanded) SB onto the Gallery Deck

The menu entry for the command will open and close the SB, but it does not open to the expanded Gallery deck, just the collapsed SB.  And then it is not clear the SB Gallery deck is getting focus in response to the .uno launch from menu.

Not clear that the <F11> toggle is behaving either. It will toggle open the SB Style deck from closed SB, and it will close SB when <F11> again used.  But if the SB is opened to Gallery from menu or if .uno:Gallery is assigned to shortcut--the Style shortcut <F11> is non-functional and SB remains on Gallery.

Jim R. had done the set of shortcuts (<Ctrl><Alt> 1-9) for the SB deck Tabs for bug 84502, and those only function when the SB is active.  Did the SB Tab behavior from other UNO get crossed up there?

For me the shortcuts function when the SB is active or inactive.

I wonder if this worked when it was merged. Nevertheless, here is a patch to make it behave as expected:

F11 doesn't work in the sidebar when focus is in a deck other than the Styles deck. F11, .uno:DesignerDialog, isn't a toggle command, although we sort of made it so in enhancement bug 101915. When focus is in the Style deck and F11 is pressed the sidebar closes. But, if focus is in the edit window and the Styles deck is visible, pressing F11 will not toggle it closed. I think it's always been this behavior even back when it was a dialog and not a deck. One way to make F11 a toggle command is to use .uno:SidebarDeck.StyleListDeck for the keyboard shortcut. Menu > Tools> Customization > Keyboard tab Sidebar Decks StyleListDeck. 

Or we can hard code this in sfx2/source/sidebar/SidebarDockingWindow.cxx by doing this in SidebarDockingWindow::EventNotify:
  
  if (".uno:DesignerDialog" == aCommand)
  {
     comphelper::dispatchCommand(".uno:SidebarDeck.StyleListDeck", {});
     return true;
  }

Jim Raykowski committed a patch related to this issue.
It has been pushed to "master":

https://git.libreoffice.org/core/commit/d7cbd78a810b263fd2f53ca58ec678008a387e22

tdf#149050 fix .uno:Gallery not opening Gallery deck

It will be available in 7.4.0.

The patch should be included in the daily builds available at
https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
information about daily builds can be found at:
https://wiki.documentfoundation.org/Testing_Daily_Builds

Affected users are encouraged to test the fix and report feedback.

Guess we can resolve fixed now.

Thanks Jim!  The Gallery menu entry behaves now. 

The <F11> toggle remains non-affecting when SB is on other decks, should probably adjust as Jim suggests comment 3; otherwise the <Ctrl><Alt>+2 for Styles deck, or better the <Ctrl><Alt>+4 for the Navigator are very handy--if unknown--shortcuts. 

An aside: looking in the Customize -> Keyboard panel at the 'Sidebar Decks' panel, not all the functions from bug 84502 are showing their assigned shortcut keys. The UNO responds to the shortcut, but the Customize dialog is missing the assignment.

Decks that are global show their key assignment when the module radio button is set on LibreOffice(Dev).

Duh, of course. Makes perfect sense for the module specific decks to be separate from the global decks--Properties, StyleList, Gallery, Navigator are global <Ctrl><Alt> 1-4, respectively. 

Shortcuts for Decks specific to the module start after those and are controlled by the radio button.

Thanks for reminiding me of how you'd set it up.

Here is a patch that shows the keyboard shortcut for sidebar tabbar tab buttons that have them:
