The new names are shorter and less generic, so they're better suited for shortcuts. Chrome OS already includes shortcuts to the apps, but you can manually install them in Chrome - Docs, Sheets, Slides. The Chrome apps only create a new document, spreadsheet or presentation. If you're using other browsers, you can simply bookmark:New document, New spreadsheet, New presentation.
