Educate me... Function Keys

[AlwMVMO]

See if you can use the keyboard to access the top pull down menus
When you press and hold the ALT key one of the characters in each Menu will be underlined. 
Most of the time it will be the first character but sometimes it will be a different character.

example:
ALT-D will pull down the   Draw   menu
then ALT-L will pull down the   Line   menu
then ALT-L will select the   Line   option.

example:
ALT-E will pull down the   Edit   menu
then ALT-E will select the   Edit   option
then ALT-D will select the   Edit Object   function       < - - - note character d is underlined

Then see if you can assign these keystrokes to the function keys.
Google "How to Assign Shortcut Keys on a Mac" for help.

p.s. Macros won't help you here.
