## Renaming Things If you point at the name of the thing, a couple of buttons will appear: the red cross simply removes the thing from the current selection; but the pencil allows you to rename the thing. Pressing the rename button takes you to an inner space with a keyboard that you can use to type in a new name.

The form also appears on the desktop view of FirstStage allowing you to type with a real keyboard if you prefer. ## Multiple Selection You can also change properties for many things at once, by selecting them with the [Selector](https://docs.moviestorm.co.uk/firststage/basics/core-tools/selector): all things selected will show at the top of the screen and the common properties shared by everything in the selection can be changed.
