This is cool to look at but its worthless to use to learn Morse code. Actually learning requires recognizing audio patterns not quickly translating characters into words from a flowchart.

I think the charts were meant for an inexperienced or almost untrained operator (civilian in wartime e.g.) that could write down what they heard, then use a chart to decode it and maybe even send a reply.

No sources, though.

How does one distinguish between "Tea" and "X"?

Both are dash dot dot dash.

Are there gaps between words or letters?

International Morse code is composed of five elements:

  • short mark, dot or dit: "dit duration" is one time unit long
  • long mark, dash or dah: three time units long
  • inter-element gap between the dits and dahs within a character: one dot duration or one unit long
  • short gap (between letters): three time units long
  • medium gap (between words): seven time units long (formerly five)

So in between every sound is a silent dot, between letter a silent dash, and every word ~2 silent dashes

This is awesome.

If anyone could explain the reasoning behind it; that would be even more awesome. It always just seemed random to me.

It's effectively a Huffman tree based off the frequency letters occur in the English language used to minimize the overall symbol length duration of each letter in a message.

The reason behind morse code? It was created to transfer messages through telegraphs

Pretty sure he means the dot and dash combinations. As in, why 'A' is not dot, since it's the first letter of the alphabet?

This is what I mean and am only now realizing I phrased very poorly…
