I have assigned a hot key to open the Vault Switcher. But I cannot navigate the Vault Switcher using my keyboard, so I have to tap instead.
Proposed solution
Please make it easy to navigate the Vault Switcher using the keyboard.
The intuitive and simple thing would be:
Arrow keys to select a vault
Enter key to enter the vault
Ideally, I think you’d also make it possible to skip the arrow keys, e.g. make the vault list a numbered list, and then users can just press the relevant number to immediately enter the vault.
An even nicer option would be to make it possible to assign a hotkey to directly open a particular vault (without having to open the Vault Switcher first).
I agree, coming from Sublime Text it’s one of the first things I noticed.
Third party solution: in the meantime I found this other thread Opening another vault with keyboard only? - #5 by samueldee which mentions a feature request to Quick Switcher++ which has been implemented via action “QuickSwitcher++: Open in Vaults mode” (bind a shortcut to it, such as Sublime Text style Ctrl+Alt+P). However, it only finds existing vaults in the list of known vaults. To open or create new vaults, you still need the native vault switcher (but since the issue is about productivity switching about the same vaults again and again, it shouldn’t be a problem).
This has been solved with the recent Obsidian version.
There are now built-in commands for Open vault (keeping the current vault open), Change vault (close and switch) and Manage vault (which opens the vaults window).
You can give keyboard shortcuts to them, so it is now possible to switch vault with keyboard only.
