Hello! I'm making a search bar for my mod and I was wondering where I can find how to implement a ctrl + a to select all and being able to hold delete. I'm currently using an integer to store my keyCodes and I was wondering if there was a way to check if a combination of keyCodes are typed and if you can hold them down.

I don't know why you're reimplementing a system that has already been implemented.

Having messed with Minecraft's text fields before (and having to dicker around with multi-line selections) I can tell you aren't using the UI widgets that already exist.

I'm using the GuiScreen keyTyped function in an extended class, because the search bar is in a Gui. This is the code that I currently have

 

	public void keyTyped(char typedChar, int keyCode) {
        if (focus) {
            if (keyCode == 28) {
            	focus = false;
            } else if (keyCode == 14) {
                if (!typed.isEmpty()) {
                	typed = typed.substring(0, typed.length() - 1);
                }
            } else if (ChatAllowedCharacters.isAllowedCharacter(typedChar)) {
            	typed += typedChar;
            }
        }
	}

 

No seriously, have you even looked at GuiTextField?
