TabStack is a Sublime Text (build 4100+) package for switching between open tabs using an MRU-style stack. It keeps tab order per window and previews tabs in the quick panel before committing the switch. It also preserves tab ordering across sessions and supports multiple selections. When closing a tab, TabStack restores the previous selection.
TabStack is available on Package Control.
Open the Command Palette,
select Package Control: Install Package
and find "TabStack" in the list.
The key bindings are:
ctrl+tabctrl+shift+tabctrl+upctrl+down
These are not configurable
because the release detection of the ctrl key is hard-coded.
Press one of those shortcuts to open the tab stack quick panel.
Use the same keys to move through the list while it is open.
Release ctrl to commit the selected tab.
Press ctrl+escape to cancel.
TabStack supports Linux, Windows, and macOS. It polls the native key state APIs to detect modifier release events.
On Linux, detection uses the X11 key state API,
so Sublime must run under X11 or XWayland
(for example with GDK_BACKEND=x11).
Note that this has not been reported to work yet.
A native Wayland session exposes no way to poll global key state (a deliberate security restriction in the protocol), and Sublime Text does not provide a key-release API to plugins. See also the related upstream issue.
Support for sheets that are not backed by text, i.e. HTML sheets and image sheets, cannot properly be monitored before ST build 4205 due to missing API support.
