By selecting 'factorial' and pressing alt-m, I see the origin of factorial.
However, I do not see 'm' on the list of commands when I press right mouse
button. What does alt-m stand for?
This isn't actually a Smalltalk question but a general GUI one instead. There are two ways to invoke commands: you can press the right button on the mouse and then point to the option you want in the menu that pops up or you can use a keyboard shortcut to save time.
"pressing alt-m" means you hold one of the two keys labeled "ALT" on your keyboard and then you press "m".
If you use the right button to pop up a menu, you will see that many of the entries have an indication of what the corresponding shortcut is. So you can use the menus to see all possible commands and then the shortcuts to go faster the second time.
