Auto typing focus on const value type-in
When a const value node is added to a function-style graph, the typing focus should be automatically set on that node's value type-in control.
The only specific situation where this would not improve the situation would be when the user wants a zero. In which case, they would just hit enter an extra time.
So to add a new const float value of 1.3..
With this feature: tab, f, enter, 1.3, enter
Without it: tab, f, enter, move mouse over to properties pane, click type-in control, 1.3, enter.
