CTRL+4 and also CTRL+5 not operating in OSX

Recently, I've seen that my MacBook Pro 5,1 (mid 2009) running Snow Leopard 10.6.6 does not react when I push CTRL+3 or CTRL+4.

When, as an example, I'm in an application that has no bindings for the CTRL - keys and also I push CTRL+2, I will certainly listen to the OS X sharp audio, due to the fact that the application obtains a key mix it does not recognize. This holds true for all CTRL+n mixes, other than 3 and also 4.

Despite where I attempt it bdsh also in position where pushing the abovementioned key mix would certainly have a real result bdsh absolutely nothing takes place.

Yet it does not simply appear to overlook the keypresses ; it numbs the keyboard. If I, as an example, hold CTRL and also press 5 and also 6, I will certainly listen to 2 signals. One for each and every unidentified key mix. If I after that do the very same, yet with the numbers 4 and also 5 (which generally are receptive), there is no audio. Actually, whatever key I push when CTRL is being held back after having actually pushed 3 or 4, absolutely nothing takes place.

In the beginning I figured I possibly included some faster way to the key mixes by crash, yet I can not locate it anywhere. In System Preferences → Keyboard , I've recovered every little thing to default, yet that really did not appear to transform anything.

I've attempted with both the onboard keyboard, a cordless Apple bluetooth keyboard and also a cabled USB Apple keyboard.

I assume this is a bug in Mac OS X and also has something to do with the means the keyboard faster ways for Spaces are refined. Attempt this :

  • Make certain Spaces is activated in the System Preferences with the typical 4 rooms format, and also typical key mix for switching over to a room.
  • Open a folder in the Finder.
  • Press and also hold CTRL, and also push any one of the number keys. If you push 5, 6, 7, 8, 9 or 0 first you will certainly get a beep. Very same if you push among those keys once more (still holding CTRL). If you after that press 1, 2, 3 or 4, you will certainly switch over to that room number ; or simply remain in that room if you were currently in it. If you after that push any one of 5, 6, 7, 8, 9 or 0 once more, it will not beep any longer.

If you merely switch off Spaces, the above will not take place and also whatever order you push the type in, they will certainly remain to beep. If you transform the variety of rooms to just 2, after that 3, 4, 5, 6, 7, 8, 9 and also 0 will certainly offer you a beep till you've pushed either 1 or 2. I do not recognize of an application in which those keys have a non - Spaces capability and also would certainly do something valuable apart from beep, so I have not had the ability to attempt what takes place in such an application. Regardless, I do not assume you require to stress there is something incorrect with your keyboard or the means you've set up the keyboard bindings ; it appears to be a bug in Mac OS X.

Edit : Try the above in a new folder in which you've developed folders called "1", "2" and more. I locate the Finder is actions in this instance rather weird : if you push CTRL - 8, it will certainly beep yet additionally switch over the option to the folder called "8". Yet once more, pushing 5 via 9 will certainly neither beep, neither transform the picked folder as soon as you've pushed any one of 1 via 4.
