Scrollwheel (when using the brush or other drawing tools)
increase/decrease stroke size: Pressure sensitivity for non-stylus folks.
zooms in/out. Clicking on the zoom buttons is a hassle and some people don’t have mouses. Also, it’ll be nice to have the zoom focus on where the cursor is.
Centers and fit the viewbox.
toggles between objects on the same layer: Sometimes it’s hard to select individual objects when they are close to each other.
ctrl+enter (when using the text tool)
finishes the text box.
double click (using the select tool too)
edits the selected text box.
undoes the previous action. A single keypress rather than two saves a lot of time when it’s probably the most common thing that people do.
toggles on/off onion skinning.
opens the project in a new tab is the file is .wick. Otherwise, add the file to the assets.
middle click (on a frame)
turns it into a keyframe.
Along the rest of the shortcuts from 0.10, which I’m sure you guys are already working on.
