It would be useful to have keyboard shortcuts to switch between code editor tabs. I would propose Ctrl-PgUp to switch one tab to the left and Ctrl-PgDn to switch one tab to the right, as it is used by Firefox, Chrome, etc. I see from the comments that this has already been implemented as Ctrl-Tab/Ctrl-Shift-Tab, but it would still be useful to support Ctrl-PgUp/PgDn as an alternative. Thanks.
