Right-clicking a file or folder brings up a context menu, but also selects that item and displays it in the editor.
Example of when this is an issue:
I am drafting prose in the editor. I want to open a research text in a second editor.
I right-click the research text to select “Open in Other Editor” but it’s too late - the reseach has already appeared in my main editor!
(If there is an option to switch this off, then it ought to be set by default.)
