I have a document with 350 anchored objects. I want to increase the scale of each by 20%. How do I do this?
There might be a more effective way (most likely through scripting), but the fastest way I can think of without scripts is:
1) As preparation: assign a shortcut to the "Transform again" function (Object > Transform Again > Transform Again). Shortcuts are assigned under "Edit > Keyboard Shortcuts"
2) Select your first object, and scale it to 120% (Object > Transform > Scale).
3) Select the next object, and press your assigned shortcut to repeat the scaling operation. Repeat for all objects.
To my knowledge, you cannot select multiple anchored objects at the same time, so doing it one at a time is the only way. The shortcut at least lets you repeat the scaling operation, so you don't have to manually access the scaling dialogue and enter 120% every time.
