In PowerPoint, is there a keyboard shortcut for bulleted / numbered list

During Presentations:

A or = : Show / Hide Pointer

E : Erase Screen Annotations

H : Advance to Hidden Slide

B or PERIOD : Display a black screen, or return to the slide show from a black screen

W or COMMA : Display a white screen, or return to the slide show from a white screen

TAB : Go to the first or next hyperlink on a slide

You could use a VBS script to do this with sendkeys.

Create a text file with a .vbs extension, and create a WScript Shell object, then use sendkeys. I just tried this with ctrl-shift-escape to open task manager:

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.SendKeys "^+{ESCAPE}"

Found the info here.
