When I was programming on Python, the "up arrow" key could copy a previous command line that I have entered, but I'm not sure if such a shortcut exists in Maple.

For example:

INPUT: 2+2

OUTPUT: 4

Presses "up arrow key"

2+2

Thanks,

Say I want to find the derivative of x^2+2x-3 when x = 2

i.e. f'(2) where f(x) = x^2+2x-3

How would I do this?

Thanks.
