Edit property of opacity without mouse
on Jul 29, 2017 at 3:19:46 pm

Hi,

is there any way of changing propertys without touching the mouse?

When pressing "t" or "p" or so it just opens the opacity or position, but i still have to click on the value to change it...

I suppose there's mental telepathy... good luck with that one! You are pursuing a fruitless quest. Computers use mice. Get used to it.

Ctrl+Alt+ minus or plus keys. add shift to move in X10 Increments.
also Ctrl+shift+o will open the opacity dialog

it's all here: https://helpx.adobe.com/after-effects/using/keyboard-shortcuts-reference.ht...

For the opacity you can use an expression that fades in and/or out. The expression still work if you trim or extend the layer. It fades in and out over the duration of 10 frames. You can just copy paste the expression to other layers then. Here's the expression:

fadeInTime = .5; // time (seconds)
fadeOutTime = .5;

Math.min(linear(time,inPoint,inPoint + fadeInTime,0,100),linear(time,outPoint - fadeOutTime,outPoint,100,0))

If you're not sure how to use it or nor really familiar with expression, here's a more detailed take on this expression:

You can also stick a slider in the effects tab and link it to the attribute with the whip tool (look ma, no code to write!)
You are still using the mouse but you don't have to enter values and you can set the resolution of the slider so when you drag it can be very very fine grained unlike the clicking and draggin on the actual attribute value.

You didn't mention why you wanted to do things this way - that might help us help
