Many actions can be performed faster using contextual menus. This article explains how to make them appear.
If you are using a Mac, you need to right-click to show the contextual menu.
If nothing happens when you right-click, you probably have it disabled. You can either enable right-click on your Mac (click on Apple logo in the top-left, go to System Preferences > and switch to either Trackpad or Mouse, depending on what you're using, then find "Secondary click" option) or temporarily hold control key on your keyboard before you left-click.
If you are using iOS or iPadOS, you can bring up the contextual menu by performing a long-press on an object.
Contextual menus are available throughout the app -- when performed on an account for example, you'll be able to perform actions related to accounts: create transactions, edit or delete the account, etc.
