Například nejčastější aktivitu, přidání vlnky uvnitř řádku, +spustíme v~okamžiku, kdy vstupní text odpovídá patternu \uv{\.{\ (v\ +p}}, kde \uv{\.{\ }} znamená jedna nebo více mezer a tabelátorů, +\uv{\.{(}} je nula nebo více otevíracích závorek všeho druhu, +\uv{\.{v}} znamená jedno písmeno z~množiny předložek (viz \PB{\\{charset}}) a +\uv{\.{p}} zde znamená libovolné písmeno.
