Add functionnal keyboard support
So far the app is absolutely mouse-dependant. Those little tick boxes are nearly impossible to click with a touchscreen and there doesn't seem to be a way to toggle them with the keyboard. Hence the app is unconvenient to use without a mouse such as with a laptop or tablet. I would expect to be able to switch between the Timeline, the Details and the Summary panels using TAB, and to be able to toggle individual items in the Details and Summary using SPACEBAR

Using Ctrl + Tab you will be able to navigate between the Day, Untagged time, Timesheet and Statistics tabs and with focus on different elements (accessed with Tab) you can do a lot with arrows. Since there aren't enough votes nothing additional will be implemented for now.
