For now, in pretty much all the CS apps, you can invoke a “virtual” scrubby slider for any text edit field. Either click into the field, or click on the label next to the field to select the entire contents of that field. Then, you can use your up and down arrow keys to change the values; hold down the Shift key as well to increase the jump values. Press the Enter key when you are done.
