Hopefully this is easy to remember from left to right:
- run is F1
- stop is F2
- hide/show is F3
- save is F4
- load is F5
There are also tooltips to introduce these shortcuts to newcomers.
Most of the shortcuts are only enabled when code is visible. In keeping
with existing conventions for mouse events, we leave most event handlers
for the script when code is hidden. The only exception is 'F3' to show
code. So if you want to use a shortcut 'k' when code is hidden, you have
to instead use 'F3 k F3'.
This is all tentative and open to change. But I'll probably grow more
reluctant to change the shortcuts in a few weeks or months.
