I'm running into a curious behavior where pressing w after cmd-` (to switch windows of an application) causes the switched-to window to close, as if I had input cmd-shift-w, rather than just inputting w. This has arisen several times where I'm switching between Chrome windows and typing a message in one of them; when I switch back and start typing a word that begins with "w" that window closes.

Running Sierra (10.12.2). Reproduced on Mac Pro and on 13in Macbook Pro after restart.

I am running various background applications but wanted to see if anyone could reproduce this first.

Steps to reproduce:

  1. Open any application that supports multiple tabs and multiple windows. I tested this with Google Chrome and with Sublime Text 3.
  2. Open two windows, each with two tabs.
  3. Try using the cmd-` shortcut to switch between windows.
  4. After switching between windows with cmd-` and letting go of those keys, quickly press w.

Expected: w gets input into the window I just switched to.

Actual: The window closes, in the same way that it would if I had input cmd-shift-w.

  • Currently running 10.12.2 on a 2015 Macbook; could not reproduce the issue. Have you configured any custom shortcuts on your machines from either 'System Preferences > Keyboard > Shortcuts' or a 3rd party application? – NYKg Jan 26 '17 at 0:58

    Running 10.12.2 on a 2013 MacBook Pro and cannot reproduce unless the ⌘ key is still pressed when the W key is pressed. (Which of course should close the window Tab then.) – user3439894 Jan 26 '17 at 1:08
  • Does it happen in safe mode or in a different user account? – Timothy Mueller-Harder Jan 26 '17 at 6:04
