Proportional edit toolwith a tablet

Is there a way to adjust the fall-off of the proportional editing tool while using a tablet that doesn’t have a middle mouse wheel? Thanks.

After pressing g or s or r you can adjust the size of the proportionaledit via the pagup/pagedown keys.

hmm. thanks. seems like it used to be + and - on the num pad. is there any other way? reaching over to press those keys is kinda clunky still…
