Small typos such as commas on "e.g." and "i.e.", verb-noun disagreement fixes, hyphenation fixes, and redundancies. Could use a major rewrite in terms of voicing, tone, and clarity, should anyone want to take up that task.
lenormf did a fantastic job in the original TRAMPOLINE by providing a good density information while keeping the document short.
However, after skimming through it recently I found that these 2 basic commands (`d` and `u`) were not explicitly mentioned.
As newcomers who ask for a `vimtutor` equivalent are often redirected to the TRAMPOLINE, I thought these short additions will be welcomed.
