Using Tab to move in Control (i) AND in TextArea ?

Hi all,

In two TextArea, I need to have the ability to type a Tab character AND use the Tab character to move through the Control(i) array.

Initially I used a combination (I forgot which it was; alt-tab ?), then I had to change when Apple Broke it and I used alt-esc.

Now, with Yosemite (it seems to be Apple who made changes) it is broken one more time (some kind of text typing help, not diabled by Xojo), it is one more time broken.

Any advice ?

PS: the project runs on OS X 10.10 and Windows 8.1.
