If you're using SlickEdit's Vim emulation and trying to learn Vim, or need to hone your skills, use the vimtutor command to open a practice file that contains lessons about Vim commands. You can actually edit the file as you go. Each time the vimtutor command is used, SlickEdit creates a fresh copy of the practice file. Note that SlickEdit v13.0.1 users should install the latest hotfix.
See "Vim tutorial" in the Help > Index for more information.
