how to move one half of the pen tool?

There is PEN TOOL in Power Window, how to move ONE HALF OF THE PEN TOOL (not both hands)? IF I press ALT, it allows me to move both the hand, but how can I move only ONE HAND of the PEN TOOL in power window or any selection tools, where there is the pen tool. (e.g in photoshop we can use CNTRL to use one hand)

Those are handles, not hands. (Had me fully confused until I saw your image.)

CTRL will allow you to adjust one at a time.

I already tried it before, didnt work. Pressing CTRL do nothing to single handle but what happens is that if I press CNTRL, then Press and HOLD ALT, the single handle starts moving. So, I m confused, this is not how it shud work.

Just tried it again in Studio 17.1 for Windows with a Curve Power Window on the Color page. Ctrl+Click allowed me to select and move a single handle.

Ahh, it's possible things did change.
