Countdown in Javascript/ jQuery: Tick Tock

So recently I had to make a simple countdown program for the Intra-Mun that was happening in my school..
So even after joining college I went back to school cause I really missed it as well..

Anyways let me first give some details about the functions:

• Set hour/min/sec
• Start/Pause/Reset(to the last entered time)
• I added two buttons for presets of 30 secs and 1 min.
• remove the input menu with keyboard shortcuts
• And I made keyboard shortcuts for all functions cause I knew i would feel too lazy to click..
• Coded in Javascript/jQuery with some css 
• And after time reaches 0.. there I added a nice pop-up notification!

Here is how the entire page looks like when timer is running:

And then there are lots of keyboard shortcuts.. honestly I added them because I was feeling bored and I wanted to see what else I can do to make it more interesting..
In case the user forgets.. one can always press the "h" or "H" key on the keyboard..
Matthew 7:7 "Ask and it will be given to you.."
Same right here..

A lovely pop-up telling you which key does what

And then there is the input menu of course which arrives when you start or press "M"/"m" to bring it.. or "x"/"X" to get rid of it and clear the screen..

Of course all these are pretty simple.. But I thought since I spent my time on this.. hopefully someone might be able to use this as well in the future..

PS.

This is the notification when your time runs out.. ;)
