You can easily customize the shortcuts for your keyboard or use, as I do, a FCP X keyboard cover to get those shortcuts. For example “Play Range” is – (the key next to right Shift) on Swedish keyboard. You can check the shortcuts from a site that sells FCP X covers or keyboards, like KBCovers: https://kbcovers.com/final-cut-pro-x-keyboard/
Use the “Open in Timeline”-command. You can find it in the contextual menu by right clicking a clip.
