Press Ctrl+Alt+O and your problem will be solved.I had a problem with InDesign. Once I was working on a Hindi Book, doing type-setting and formatting with InDesign CS4, I faced a problem like the short-keys was not working. I pressed and pressed but nothing was gonna work. I asked my seniors but they said that keyboard have problem, I changed keyboard, but the it didn't worked. My keyboard's shortcuts, ctrl+1, Alt+scroll, etc., was not working, Why?
Reason: When we work with InDesign we use lot of shortcut keys and functions, and sometime pressing any wrong key disable the shortcut keys function. To enable that function we have to apply below mentioned trick.
Solution: For the solution of the problem we just need to press Ctrl+Alt+O and our problem will be solved. And if it don't work go to Edit menu and then click on Keyboard Shortcuts. Now again you need to press Ctrl+Alt+O.
Using Shortkey in InDesign makes our work faster and smarter and if you are working without short-keys then you are not using InDesign. If you want to know any shorcut for any option or function in InDesign then just write your query in comment option and I will give you better solution for this.
Thanks for your time.
