Keyin to change the selected text to certain angle

Don't know of a key-in, but you can create a selection set, then use the properties dialog to change all of them.

Hi, thank you for your replay. All these standard methods (unless keyins, macros) are known by me.

There is no keyin to do that because the text could be at an unknown rotation. The calculation between the random angle and your desired angle requires the logic of a VBA (like the excellent ActiveAngleAssistant).

May I ask why that tool is not suitable for your purpose? What are you trying to accomplish that the macro will not do?

I need to do this in a batch process without user assistance.

Record a macro using the selectby and properties dialog. Batch away.
