Can I remember functions of Powerpoint and Excel which I rarely use?

• Many functions in Powerpoint and Excel are generally not used and hence forgotten (all tool bar menu)

You have to live with that. You will mostly remember those things which you use frequently.
Tool Bar menu is self explanatory. So it is not difficult to use them, if you don’t remember them too.

Best way to use them if you don’t remember is:
- Type what you want to do in google and you will find something relevant.
- If you don’t have Internet then search for what you want to do in the Help File.
