Improve the way anchor points are removed

[Friksel]

1. In the README it says alt + d to remove an anchor point. Working on Windows in Chrome this isn't working here. After selecting an editor and an anchor point on the curve the point is not deleted with alt + d. Neither with ctrl + d or shift + d. Am I missing something, or is this an issue?

2. In most graphical software I use deleting anchor points happens with the DEL-key. Could this shortcut be added as an additional keyboard shortcut? To me that would be a lot more descriptive and intuitive then a double keystroke for something we use a lot.

3. It would be nice to have a delete-button in the curve-editor interface too. Working with a lot of different software it's hard to remember all different shortcuts and keys aren't always the prefered way to me. Having a key to remove an anchor point would not only be convenient for graphical use, but could also show the shortcut key on the tooltip, so you get to know the shortcut after use more often. Instead of having to go to the github readme.

That said, very impressive workflow like this and beautiful layout of both the curve editor as the player. Thanks a lot for all the effort you obviously put into all of this! It's a lot of fun using mo.js! I like it a lot. Keep up the great work! :)

1. Need to to some browser testing. It works fine on Firefox 67 on a Mac at least.

2 and 3. Good ideas. We'll add it in the backlog.

In some browsers, alt+d selects the URL and thus it seems to be breaking the delete point code.
I am on Windows 10 + Chrome 88

Hi @skymen,

Yes we know there is some issues with current shortcuts on the player.
We need to refactor them. Thanks for giving your feedback on this 😉
