Google Calendar Keyboard Shortcuts
Google Calendar recently got new look. It tells me the shortcut I wasn't aware: Mode switch using A/D/W/M/Y/X keys. The UI gives indicators to tell the shortcuts. The cumbersomeness of mode switch had frustrated me for a long time, but not anymore!
I'm on the cynical side on Material-ization and/or mobilization the desktop Web UI, and I don't think Google Calendar isn't particularly loved product, but this change is decent and I do like the product a bit more than before now.
