She rummaged in her pocket looking for her keys.
Literal
She [topic-は] keys [object-を] looking-for pocket [object-を] rummaged.
Two key verbs side by side — 探す ('search for, look for') and 探る ('feel around for, fumble through'), both written with the same kanji 探 in different verbal forms. 探す is for actively searching for an item you intend to find; 探る is the more groping, exploratory action — feeling through a pocket, sounding out a possibility. Pairing them here shows the relationship: she's *looking for* (探す) the keys, *rummaging through* (探る) the pocket. The te-form 探して links the purpose (looking for keys) to the action (rummaging in pocket).
