HOLD THE PHONE
I have found a solution.
- In chrome os, go to settings -> keyboard.
- set alt key to disabled
- turn off “enable auto repeat”
- Presto! Things work as desired.
The downside is that the alt-key now does not do what one would expect it to do in other situations. I work with a code editor a lot of the time, and the alt key is useful for traversal. But, for now I’ll take it!
edit - this also makes some other key combos unavailable in gravit, basically anything with ctrl+alt+*, like show/hide grid, rulers, etc…
edit 2 also, to delete an object from the artboard, chromeos users must use alt+backspace. this no longer works…
edit 3 Sorry, I’m learning as I go here. One can also use ctrl+x to remove an object from the artboard.
