I don't know about the tooltip, that usually shortly explains the icon
in the toolbar.

Completion of macros is available with C-M-i, for example you write:

\use and press C-M-i then you get possible completions:

Click on a completion to select it.
In this buffer, type RET to select the completion near point.

Possible completions are:
usebox
usecounter
usepackage

If you write:

\usep

and press C-M-i it completes to \usepackage

Now to get an incremental drop down meny I may recommend using package
`ivy' from GNU ELPA as that would open up the possible completions
when using macro completion key bindings C-M-i 

See screenshot attached, as it shows possible incremental completion
next to the cursor, that is `ivy' package doing it.
