If I solve d/dx of some function, and then want to copy just the function, not the whole d(function)/dx statement to use elsewhere, how do I do this?
Copy copies the whole line, can't figure out how to grab specific portion of line that I wish to use...

Open it in the command line. Press COPY, you can then position the cursor and press begin/end to select specific areas.
Or, hold down your finger for a bit and drag to select.

If you used d(function)/dx then want to go back and just copy the function, I copy the whole d(function)/dx to the command line then
SHIFT COPY BEGIN END ESC SHIFT PASTE 1 ENTER. Sometimes its easier to just copy to the command line then backspace delete stuff you don't want.
If I know that Ill be using the function more than a couple of times , Ill first define it (in CAS) using
f(x):=function. Then, I can use
d(f(x))/dx or
f'(x) and still have
f(x) handy and separate.
There are probably other useful methods.
