I am currently adding some pretty generic hotkeys to a visual editing app. You can select elements on a an artboard, move them around and edit their properties. Not too far into my journey I encountered the following problems:
- The Delete hotkey - I mapped the Delete hotkey onto the backspace and delete keys. When I now have an element selected and change some text property and hit backspace, the element gets removed rather than just changing the text property. I can think of a few solutions for this problem:
- The input event fires before keyup. Remember that an input event happens and consider that when using delete. Pro: only done once. Con: Hacky and Procedural.
- stop propagation on input event. Pro: clean, Con: Has to be done for every single element.
- remember that a text input is focused and do not listen to key press events then.
- The undo / redo keys: The app also has history buttons. The state of the currently edited project is persisted on a server. I find it tricky to figure out when to identity undo keys, apply the undo operation and persist the data afterwards - without having an undo operation push to the redo queue BUT persisting the state of the project.
Do you have any experience with these complexities? How did you handle this.
