`tt(\{)var(N)tt(})' may be used to protect the digit from following
digits.
By default the previous source or replacement string will not be offered
for editing. However, this feature can be activated by setting the style
tt(edit-previous) in the context tt(:zle:)var(widget) (for example,
tt(:zle:replace-string)) to tt(true). In addition, a positive
numeric argument forces the previous values to be offered, a negative or
zero argument forces them not to be.
The function tt(replace-string-again) can be used to repeat the
previous replacement; no prompting is done. As with tt(replace-string), if
the name of the widget contains the word `tt(pattern)', pattern matching
is performed, else a literal string replacement. Note that the
previous source and replacement text are the same whether pattern or string
matching is used.
For example, starting from the line:
