How do I make a discontinuous selection of multiple files in PyCharm's project view (MacOS 10.5+ keymap, MacOS Mojave, Apple Magic Mouse), say to select two file to compare, etc. I can extend a selection with Shift-click, but there doesn't seem to be any way to select one file, then click on another arbitrary file to include it in the selection? The MacOS standard for this is Cmd-click, which does not work in PyCharm. I couldn't seem to find any documentation covering this, and trying various other keyboard modifiers didn't work.
It did seem like Ctrl-click (which is the Windows way) might have been trying to do this (once or twice I seemed to briefly see the selection being added to), but Ctrl-click is a MacOS system-wide alternative for the right-click context-menu feature, and the context menu would immediately pop up for (only) the newly clicked file.
How would one make a discontinuous selection of files in the project window on MacOS. Shouldn't PyCharm be mapping this to Cmd-click?
