Issues raised

[Estevo-Aleixo]

There's a bug with the first caption "block" not always editable (i.e. one user recently reported that the "First word was hard to edit".

Shift enter is weird, why not tab? (and shift tab)

ctrl + shift + arrowright moves to next caption (or hundred it becomes indeterminate) instead of selecting the word, (it is default in all text editors in windows environments to select a word with ctrl + shift + arrow)
