Really simple tip, but passing it along in the event it helps others as much as it helped me:
You can find items in Sheets using the keyboard shortcut Ctrl + F (⌘ + f on a Mac).
I found this tip today after having used the cumbersome Sheets menu options of Edit | Find and Replace, then completing the form to find a transaction.
The CTRL F key combo opens a quick search window and takes you right to the item you’re seeking on the sheet you’re viewing.
