Question: Confused about "e" (2.71828...) in Maple

I'm new to Maple and find some aspects of the syntax and UI confusing.  The manual isn't much help.  In the case of "e"...

1) If I type in:    evalf(e^1,10) by just typing the letter e from the keyboard, I get back the letter e.  But if I go into the palette and select the expression e^a, and put it in evalf that way (for a=1) I get back a numerical value for e.  I can see that one of these e's is italicized and one isn't...???

1) I read (in various places) that Maple understands it to be the value of 2.71828 *IF* you type it in as  "E".  That doesn't seem to be true.  If I type in evalf(E,10) I just get back "E".

Can someone clarify?

Thanks.
