The Edit Menu allows you access to all the standard Macintosh text editing functions.

Undo: ⌘Z
InternetMemory supports one level of Undo: you can undo the last operation but not the one before that.
 
Cut: ⌘X
Cut will delete text from its current location and place it on your Macintosh's Clipboard.

Copy: ⌘C
Copy does the same things as Cut, but it keeps the text in its current location as well as in the Clipboard.

Paste: ⌘V
Paste takes the text off the Clipboard and pastes it at the current insertion point.

Clear: ⌘B
Clear is like Cut except that no copy is saved on the clipboard. Be warned!

Select All: ⌘A
In the Content list, everything (folders, Smart Folders, and Addresses) will be selected.

Preferences…
The Preferences control how both the Application behaves. Use the "Preferences…" item in the "Edit" menu to access your settings. 

The Preferences are explained in detail in Chapter 6.
