Using Zerobrane, are there any defined hotkeys or keymaps that will jump between panes within the IDE? Like, some key to jump between several files open as tabs (jump between tabs). Another is jumping from editor tab pane over to the project pane, etc...
To jump between tabs you can you Ctrl-PgUp/PgDn or Ctrl-(Shift-)Tab. Also, Ctrl-P will open a command panel with the list of currently open files, and after selecting a file from the list press Enter to jump to the tab with that file.
Jumping to Project tab and Console is not available, but moving between tabs there can be done using the same Ctrl-PgUp/PgDn combination. I'll consider adding some hotkey to move between open panes.
Update 7/13: Something like this may work as a simple workaround (add to the IDE config file as Edit > Preferences > Settings: User):
ide:SetHotKey(function()ide:GetProjectTree():SetFocus()end, "Ctrl-Alt-P")
ide:SetHotKey(function()ide:GetOutlineTree():SetFocus()end, "Ctrl-Alt-O")
Other panes (Output/GetOutput(), Console/GetConsole(), etc.) can be done in a similar way.
