Today, I accidentally used the shortcut

Ctrl+T

(Linux, prob Windows too? MacOS maybe

Cmd+T

?) . It's a shortcut in VS Code for

Go To Symbol in Workspace

, which is like a lookup that helps you search file header titles easily (all notes and vaults), with something like

# <my-thing>

for example. I happened to accidentally do it when I couldn't find a note, and was trying to do

Superkey+T

to launch a terminal to grep through, but this did the trick. I feel ridiculous for not knowing this little shortcut prior to this.
