NirvanaHQ hotkeys popup
There are tons of tools for time and task management out there. After trying out some of them I decided to stick to NirvanaHQ. Using IFTTT I forward all of my virtual inboxes except emails to NirvanaHQ. I no longer have to check my unseen YouTube videos or new Soundcloud uploads. I find them all in one system and process them regularly.
I have written a little userscript, which adds a “Hotkeys” button to the top menu. It opens a popup window, containing all the available keyboard shortcuts. I find it useful, to quickly look up some hotkeys.
