Sometimes we need to hide tab controls on the layout (by setting Tab Width to 0 and Pen width to None) for specific reasons and fewdays later when we want to do some changes it becomes hard to find them.
Well, solution to this is in 2 easy steps.
1. Select one visible tab or Create a temporary tab and select it(in case there is no visible tab on the layout).
2. Press Control + Shift + A or (Command + Option + A on Mac)
And it is done.
All the hidden tabs will get selected. Now you can see where are the tabs and do the changes.
Note: This is applicable to find any hidden layout object. Only thing you need to do is to replace tab by the layout object which you want to find in the steps above.
