Release 1.16 adds several useful keyboard shortcuts that allow single keystroke movement between the various planner views. The current list of keyboard shortcuts, and their corresponding views, are:
t = Daily planner (today)
d = Daily planner (based on currently selected date)
w = Weekly planner
m = Monthly planner
q = Quarterly planner
y = Yearly planner
We'll be adding additional keyboard shortcuts in the future, as well.
Enjoy!
