I'm trying to build a WYSIWYG with Paper.js.
When I double click into a text item I want to be able to change the text. I have that working, but if I hit shift + a to get A I get shifta.

Answer 1

Characters such as !##$%^&*()_+ etc. should be handled properly by onKeyDown. To handle uppercase letters, check to see if the shift-modifier is active:
function onKeyDown(event) {
if (event.key == 'shift' || event.key == 'command' || event.key == 'option' || event.key == 'caps-lock' || event.key == 'control') return;
if (event.modifiers.shift || event.modifiers.capsLock) {
console.log('The ' + event.key.toUpperCase() + ' key was pressed!');
}
else console.log('The ' + event.key + ' key was pressed!');
}

Answer 2

function onKeyDown(event) {
if (event.key == 'shift' || event.key == 'command' || event.key == 'option' || event.key == 'caps-lock' || event.key == 'control') return;
if (event.modifiers.shift || event.modifiers.capsLock) {
text.content = text.content + event.key.toUpperCase();
}else if (Key.isDown('space')){
event.preventDefault();
text.content = text.content + " ";
}else if (Key.isDown('backspace')){
var subStr = text.content.substring(0, text.content.length - 1)
text.content = subStr;
}
else{
text.content = text.content + event.key;
}
}
This is what I ended up with.
