Every time I open a new tab in SublimeText I have to take my hands off the keyboard and use the mouse to move the newly opened tab to the desired position among the existing tabs...
Surely there must be a keyboard shortcut for moving SublimeText Tabs left and/or right?
Please say yes...
It seems as if there are no shortcuts to do this.
You can see all actions and their shortcuts in the command palette (Ctrl+p on Windows). There is no such action as Move this tab to the left.
The good news, however, is that there is a plugin that does exactly this:
https://github.com/SublimeText/MoveTab
You can install it using Package Control.
