On Windows 8, the hamburger menu button is not keyboard-accessible at all: you can't access the button itself via keyboard, and you cannot navigate menus with keyboard :( nithin, are you talking about the hamburger menu button? How is it accessible in Linux?

sorry for being unclear description. there is no shortcut for menu button in Linux too, i guess. i am talking about, once you open the menu on the right corner, the popup menu will be visible. hover over one of the menu item using mouse, then try navigating up and down

Yes, we are talking about the same thing. Even the same problem. It's because I started out on the Options Dual Menu (aka Preferences on Linux) that I could not move the focus at all. Only starting out on the simple popup menus works. So this is the bug: STR / -> Actual result Scenario A) starting out from dual menu: keyboard focus stuck on dual menu 1 click on hamburger TB menu button 2 hover over New Message dual menu -> message submenu opens; close it with cursor left -> now New Message dual menu is highlighted 3 press cursor down -> nothing; New Message dual menu stays highlighted, but focus is not moveable up/down by keyboard Scenario B) starting out from simple popup menu: keyboard focus skips all dual menus 1 click on hamburger TB menu button 2 hover over Save As simple popup menu -> Save As submenu opens; close it with cursor left -> now Save As simple popup menu is highlighted 3 press cursor up, trying to select New Message dual menu -> only simple menus or simple popup menus are highlighted -> dual menus like New Message are never highlighted, i.e. not keyboard accessible. Scenario C) keyboard focus also cannot be moved from the left half of the button's menu to the right half, and vice versa; focus is always stuck in the active column Scenario D) Well, the whole thing isn't keyboard-accessible anyway, because you can't even get there with keyboard only: -> no keyboard access (e.g. shortcut) to open the hamburger button Expected Result I suppose if we are taking the hamburger button serious (which may not always be true for everyone), then it should (must?) be keyboard accessible, like any other part of our app (in theory...). Alternatively, we could argue that the hamburger button is mouse-only; the keyboard alternative is using the traditional main menu, which is very accessible... There's an existing bug (probably XUL) for Scenario A) and B), assuming they have the same cause.
