Keycode e which

Warning: The purpose of these new additional rules is for making users whose keyboard layouts map unicode characters to punctuation keys in a US keyboard layout can use web applications which support Firefox only with ASCII-capable keyboard layouts or just with a US keyboard layout.

Otherwise, the newly mapped keyCode values may be conflict with other keys. For example, if the active keyboard layout is Russian, the keyCode value of both the "Period" key and "Slash" key are KeyEvent. If you need to distinguish those keys but you don't want to support all keyboard layouts in the world by yourself, you should probably use KeyboardEvent. The value of keyup event is 0x00 0.

These keyCode values are the same as the Insert key's keyCode values. Chrome and Safari map them to the same keyCode values as Mac's keys. Firefox sets for them the same keyCode values as the PC's keys. If the keys cause proper keysyms, these values must be same as IE. Note: Recent Mac doesn't have a NumLock key, and therefore state. That's why the unlocked state is not available. Gecko defines a lot of keyCode values in KeyboardEvent for making the mapping table explicitly.

These values are useful for add-on developers of Firefox, but not so useful in public web pages. On Windows, some values of virtual keycode are defined reserved for OEM specific key. They are available for special keys on non-standard keyboard. In other words, some values are used for different meaning by two or more vendors or hardware. So they are not useful for usual web applications. However, I did not have the chance to check it on IE Edge. Today I did. But first to get back to the fix I had to implement in order for the colored box to render to the page.

It had to do with the keyCode property. In my case, it worked in Chrome and Safari , no problem. But then I forgot to go into Firefox and check there.

I even presented it in class! Rendering of the colored box depends on the keypress event , so it simply did not appear. I wracked my brain about it. I changed my conditions over and over, and then suddenly I remembered having come across a thread on CSS Tricks about e. There were no examples there, simply talk about it.
