+- `projectionist_open_alternate` - open an alternate file for the current file.  
+In Sublime Text 4 this command supports `"mode": "side_by_side"`, to open an alternate file in a side-by-side view.
+This command is also available in the Command Palette (`Projectionist: Open alternate`) as well as in the Side Bar.
+In the Side Bar there is also an option to jump(reveal in Side Bar) an alternate file rather than open it.
