Go to a page with an HTML input form, like google.com. Click on any link, and then use alt-leftarrow or another method (like sensiva.com mouse gesture) to go back to google.com main page. Do not click on the back button. Note that no menu is selected. Hit one of the menu accelerators -- [F]ile, [E]dit etc. -- by typing in that letter. The letter appears in the input form but also pops up the corresponding menu. This is annoying because I use sensiva to go back a page, and when I want to type something into an input form I have to escape out of the accidental menu.
