These are tricky because the context you press the buttons in my not be clear. Do you want to delete in the tree, editor area, or dopesheet? Probably we will only use hotkeys for the editor area and have explicit buttons for the others.
What I mean for "Del" button (as on keybord del 😉) to do is to reflect the "Delete" button on the lower right side of screen whenever it appears. So for example when I select a bone and want to delete it i do not need to fly my mouse way over to the side of the screen.
X, C, V, B switch between tools. Keep in mind that right click toggles to the last selected tool. This greatly reduces the need to switch tools with the keyboard or toolbar buttons. We will document these things soon.
Ha! Was looking for it under 1,2,3 and F1, F2, F3 (inkscape style) 🙂.
Are you sure about entering numbers? I don't see that X.0 is required. Be sure to press enter to save the value, if you click away it will revert to the old value. We may change this.
I think you're right. I was clicking away instead of enter pressing and got confused 🙂.
So much of Spine really requires a mouse, I don't think it is a good fit for Android. You are right that it could run there though.
You might be right, but then again I'd like to give it a try there if it was possible. And could be your "Look! We even run on android!" 😉 Even more if you consider a pointing stylus for a tablet like in galaxy note for example than that could really work.
