Hi Meyex,
If you have any parameter (field) selected, you can type in x=25 whereby the x stands for the value that is there already and its adds 25 to it. That could be also done with * / + -
The rotation around an axis, again here, the parameter works as if you would adjust the numbers in that field.
In the moment a parameter field is given, and formula can be used. See appendix in the Help content.

If you scroll down a little bit, you find some more tips, even to be used with many objects that share the same parameter
“The following variables are available:
x: Represents the parameter’s original value
num: Represents the index value. The selected elements/objects will be numbered
tot: The total number of selected elements/objects
rnd(value): A random value between 0 and “value” will be ascertained”
However, if you are looking for a short cut that allows for an input without using the parameter fields, I guess there is none.
All the best
P.S.: Snapping might be worth to look into it as well.
