Naming things is hard! Use AI Assistant for even better naming suggestions. Open Refactor | Rename ⇧F6 (macOS) / Shift+F6 (Windows/Linux) to rename a variable or method. If you are logged into AI Assistant, you'll see its naming suggestions at the bottom of the list. Select the suggestion you want, using the arrow keys and press ⏎ (macOS) / Enter (Windows/Linux) to select it. If none of the suggestions are quite what you want, you can also type the name you want yourself.
