We ran into this at Google:

Currently, VSCode will use F10 (like many debuggers) for stepping over on Electron, but Alt+F10 on Web. The rationale, according to the code comment, is that browsers will not allow you to bind F10:

I believe that is not fully correct:

• VSCode itself uses F10 (curiously exactly when in the browser), to focus the file menu:

  vscode/src/vs/workbench/browser/parts/titlebar/menubarControl.ts

  Line 443 in 60fe2d5

  primary: KeyCode.F10,

• I changed the shortcut to F10 in the settings, and in my browser (Chrome on OS X) it worked fine - maybe it does not work on specific browsers?

@isidorn, you removed F10 for step over on web in f0cf34e - do you recall the exact reason?
@sbatten, you added the F10 for application menu on web - why is this only on web?

I would like to better understand if we can somehow make this work, as users generally expect F10 to step over in debuggers, and having to type Alt+F10 for step over, when e.g. step in is just F11 is causing friction.
