Acting on a match
In Vim, a search puts the cursor at the start of the match, and changing the text takes a second step to say how much of it you mean. In Helix that second step is already done: the match is the selection.
That means any command that acts on a selection works directly on a search result:
cdeletes the match and drops you into insert mode in its placeddeletes the matchycopies it
And because n hands you the next match as a fresh selection, you can
search once and then work through the file one match at a time.
Work through the checklist below. The word the is misspelled as teh
twice in the editor — search for it, confirm the search with Enter (the
checklist ticks off the search as soon as the pattern is typed, and
Escape would leave c acting on a single character instead of the match),
change the first one, then jump to the second and fix that too.
