I very often create designs where I should have certain x-height.
Now I have to achieve this using long workaround (I do it very quick now, but now quick enough, and its not actionable):
1. Create copy of typed text with Ctrl+C, Ctrl+F
2. Outlining copy
3. Finding symbol with flat top an bottom (x or X or similar)
4. Choose Direct selection tool
5. Shift+click chosen letter
6. Deleting unwanted symbols from copy
7. Scale outline of chosen letter 1000%
8. Going outline mode (enlarged letter will probably take whole screen)
9. Shift+click at live text behind letter
10. Set desired x/cap-height as height of selected art multiplied ten times
11. Shift+click live text
12. Delete outlined symbol
13. Exit outline mode
Thirteen steps!
