There's nothing to do but accept that most of us work in complex computer environments. Unfortunately, sometimes we're running system software which uses a keystroke which duplicates one which we're expecting to use in InDesign. Or, you're running some Firefox plug-in which for security reasons, disables keyboard shortcuts. Nothing InDesign can do about that.
It's up to us to figure out where the conflict is:
Two methods: (1) Restart your computer, disabling your startup applications, if possible. Open InDesign first. Often, the shortcut which isn't working will again work. Then you have to figure out which one as you launch your applications is stealing the keystrokes.
(2) There also can be corruption in your system user. Create a new user, and run InDesign from there. If it works, there's a problem or a conflict in your old system.
This isn't user error, and it's not InDesign's fault. It's just stuff that happens when you run a computer.
I understand your point, I'd be pretty ignorant if I didn't. If most of us work in complex computer environments why is this a very common and widespread issue and if so many people are experiencing the same, I very much doubt it is because we're all running the same system software...
Tried (1) no good, tried (2) no good.
I was really hoping I could click on 'Correct Answer' for you mate, but that's just two more 'Hey, try this...' fixes that havent worked (that may or may not work for someone else).
Thanks anyway mate.
I guess you already tried choosing [Standard] again in the Shortcuts settings? (Edit/Shortcuts).
Second, how strange it may sound, make sure Google Chrome is not running.
I'm not sure what you mean in regard to choosing [Standard]. Where might I do that?
Note - I've just learned that another shortcut is no longer working, this time in Photoshop CC - the Step Backward shortcut OPT + CMD + Z only steps back once rather picking up on my History States in my preference settings.
The common element in your your missing keystrokes is the Option key. Any possibility is could be your keyboard Option key? Do you have another keyboard to hook up to your iMac? There have been stranger things.
This did enter my mind Steve.
I don't have another keyboard, do you know of any other way to test the keys?
Only borrowing another keyboard.
You might be onto something Steve. It's become more evident since you mentioned it, the option key just doesn't seem to be working. I wish there was another way to test it, as it will take me a day or two to borrow another keyboard. Watch this space...
A bit late to the party but have have you tried a new user account on the computer?
Thanks Bob, not late mate, I'm still working through all the 'Hey, have you tried this' fixes now. But yep, have tried a new user as Steve suggested (2) earlier, all to no avail. I'm hopeful that it might just be the physical OPTION key on my keyboard not working, but I have no way of finding this out quickly though.
"Or, you're running some Firefox plug-in which for security reasons, disables keyboard shortcuts. "
Isn't this more to do with adobe using a depreciated technique of listening to key presses? Can't find where i read that, but the fact that other apps by other vendors don't have these issues seem to support this.
Thanks Pat, but I don't use Firefox.
You write, you work with El Capitan but you do not inform us, on which InDesign you are working.
Be aware that only CC2015.2 is compatible to work with El Capitan. CS6 might run, with CS5.x and older you are completely out of luck.
// Sorry, I have seen, latest CC. Only one thing, did you update to the latest patch?
Thanks Willi, yep, all apps are up to date.
I'm about to try a new keyboard to see if that fixes the issue.
Thanks Steve. Spot on mate.
I've tried a different keyboard and my shortcuts are working perfectly. The option key on my existing keyboard is obviously not functioning.
Phew...time for a replacement keyboard.
This just worked for me! I closed all the shortcuts in my system preferences > keyboard > shortcuts that I don't use, such as capture a screen shot. When I went back to InDesign (without restarting), the shortcuts were working.
