Is Shift the only key that can change the value of keyCode?
The assumption is wrong. You see, the keydown event is fired whenever you press a key. The keypress event is fired only when said key outputs a printable character. That being said, pressing a key between a and z, for example "a" will generate: keydown with keyCode 65 (A) keypress...
What is the char represented by keycode (15) c#?
Looking at the string you have in your question in the HTML source it is written as a‏. A quick google shows that rlm is the left to right mark which is unicode U+200F (http://en.wikipedia.org/wiki/Right-to-left_mark). Combine this with other people's observation that casting to byte leaves only the final byte...
Can't use KeyCode in C#
Instead of using KeyPress, use the KeyDown event. KeyPress event will only fire on printable characters, and PrintScreen is not one of them, so it only exposes the KeyChar property, while KeyDown or KeyUp will expose the KeyCode. private void Form1_KeyDown(object sender, KeyEventArgs e) { if(e.KeyCode == Keys.PrintScreen) { MessageBox.Show("Test");...

jQuery: Need to prevent repetitive 'space bar' input
Figured out a better way to do this without any counters or anything - AND it can be done with pure Javascript JQuery $('#myInput').on('keydown', function(e){ if(e.keyCode == 32 && $(this).val().indexOf(' ') >= 0){ $('#key').text('Already a space!'); return false; } }); Javascript Equivalent document.getElementById('myInput').onkeydown = function(e) { if(e.keyCode == 32 &&...

Javascript keycode clash: “right arrow” and “single quote”
When the user presses the single quote key, the e.keyCode property is zero, and the e.which property is 39. Executing String.fromCharCode(39) returns a single quote. You want the keyCode if that property is in the event object: var keycode = "keyCode" in e ? e.keyCode : e.which; That way you...

stackoverflow.com/questions/1367700/… explains it well. keydown is only tracking the key itself, not the state of the key. If you press 'A' KeyDown generates a KeyCode of Keys.A and if you press 'shift-A' you also get a KeyCode of Keys.A.

I think what you're looking for is ng-keyup instead, this will work for you: <input type="text" placeholder="Search" ng-click="searchPop($event)" ng-keyup="typingMainSearch($event)"> According to Mozilla the keyCode property of keypress is deprecated. Also - this is why you saw 97 when clicking 'a' for instance (taken from the Mozilla link): The Unicode reference...
