This is similar to how some FreePascal programmers use CTRL-B and CTRL-E
to type out begin and end.

The problem with this is the annoying shift key strokes and strains
required to hit the ctrl key. Programmers have been hospitalized from
using keyboard driven editors like emacs... i.e. it's not a myth but an
actual recorded incident that people have literally been hospitalized from
shift key strains.
