> You do need to release the Alt key because the old menu access keys still work (invisibly), and are activated otherwise if you don’t release the Alt key. This is a backwards compatibility feature overriden by Ribbon keys, isn't it? When you hit Alt+I (Insert menu in Word 2003) you get a specific pop-up warning about that (in Word 2019 you do), and can use the invisible old menu relying on the old muscle memory. But when you use an existing Ribbon combination, it takes precedence. For example, hitting Alt+W without releasing Alt calls the View tab on the ribbon instead of the old Window menu, so you don't issue two different commands. The reason tags feel like having higher latency is because the tag appears either on release or after ~500ms of holding. But there's no input delay, it's purely visual. If you memorized it, you just touch type the combination at any speed. Classic Win32 and Office menus are prone to actual input delays, though, if implemented incorrectly (e.g. starting slow operations on opening the menu).
