What a brilliant program. Thanks very much for your efforts.

I use SMath Studio to enter and study equations relating to a wide range of subjects I'm trying to learn.
It's exremely useful to alter the values of variables and note the effects on the solutions to such equations.

I think a more convenient method of altering the values of variables would also be very useful, although the current method of highlighting such values and typing replacement values is good and should be retained.

However, in addition to the current method, I think it would be excellent if we could highlight the values concerned and use the scroll-wheel to change them.

Rolling the wheel alone could increment/decrement values by one unit, Ctrl+rolling could increment/decrement values by 0.1 units, and Shift+rolling could change the values by a factor of 10.

I couldn't find this suggestion in the other posts. If it has been suggested and I missed it, sorry for repeating.

Yes sapri, good ideas all. Being able to highlight single numbers as you suggest would be a very useful addition, as would your idea of using the arrow keys in parallel with the scroll-wheel.

The comparatively low number of reads and replies to this idea probably indicates that mathematicians are occupied with problems on a higher level, which is to be expected. However, lower level students like myself grappling with the real-world meaning of engineering/physics equations would find features like these extremely helpful.

Thanks kilele, they were interesting and useful links.

I've had another branewaive that I'd like to see combined with the idea I expressed initially on this page.

When I want to examine the effects that differing values for particular variables might have on an equation, I enter an alternate value and then use Ctrl-Z and Ctrl-Y to quickly swap back and forth between the values and watch the results. Limited but useful.

It would be exciting (literally) if we could assign numerical values to key combinations and then paste those values into highlighted data fields in variables throughout a page.

Ideally, any value assigned to any of the key combinations could be pasted over a value highlighted in any variable by pressing the key combination.

Rather than a 'copy and paste' function, I guess I'm suggesting a multi-register 'data pre-entry and paste function'. Maybe every key on the keyboard could be used to store a value. (What, too much?)

Again, I'm aware that these are not the sorts of things on the minds of mathematicians, the primary users of Smath, but they would be of great practical value for people using the program a bit differently from the author's design intention (assuming I've interpreted it correctly).

I'd like to see this implemented along with the other ideas on this page. Of course, it's obvious that incorporating such things in SMath would be a great deal of work for a single developer who's already given us so much. I'm just saying . . .
