Provides TC ID for accessibility framework feature for "shortcut" part

Goal: Improve readability which is a bit difficult because of string concatenation for accurate translation.
Root cause: In some locales, framework features name would be a word rather than a product name. Hence it need to be in the different position in a sentence.
Solution: Use whole sentence to translate instead of concatenating the string could solve this issue.
