For that, I usually do

0v$*

If you wanted something faster, you could map that to some unused
key sequence or to a function key.

I should add that I have * in visual mode mapped to a sequence of
commands that escape special characters in the visually-selected
region so that those characters don't corrupt the search pattern.

vnoremap <silent> * :<C-U>
\let old_reg=getreg('v')<bar>
\let old_regmode=getregtype('v')<cr>
\gv"vy/<C-R><C-R>=substitute(
\escape(@v, '\\/.*$^~[]'), '\n', '\\n', 'g')<cr><cr>zv
\:call setreg('v', old_reg, old_regmode)<cr>

To give credit where credit is due, that and some related mappings
were posted to the vim list in 2003 by Jürgen Krämer. I may have
made some minor modifications since.

Regards,
Gary
