keyboard shortcut to toggle between length/angle
- info displayed by link points and show measurements can be of two kinds: length and angle
- user switches between modes using a radio button in each palette
problems:
- switching between length/angles is used very frequently while working
- using a click to switch between modes takes too long: move mouse to the palette, click button
- mode switch is too permanent; user soon needs a second click to change back
- mode change in one dialog does not change mode in the other, so user sees a mixture of lengths and angles
proposal:
- add a keyboard shortcut to quickly switch between modes
- shortcut affects both tools, so all measurements on the screen are toggled together
