Repeating a change
Once you’ve made a change with c, Helix remembers it — both the deletion
and the text you typed. . repeats that change on whatever is selected now.
So fixing the same mistake in several places becomes:
- select the first one
- press
c, type the fix, hitEscape - select the next one
- press
.
No retyping. The selection decides where the change lands; . supplies the
change. It’s the same object-then-verb pattern as everything else in this
lesson, with . standing in for the verb.
Work through the checklist below.
