Note: build.sh updated to make sure that test:help build action:target doesn't also call test.sh by adding `:_all` meta-target. Note: CI will need a new help-keyman-com.sh build step to deploy web engine help. Fixes: #12347

## Description
|
|
|
|
This function is designed to facilitate filtering of keystrokes, allowing custom-coded keyboards to ignore function-oriented keystroke events that should never be used for text generation, such as for F1-F12.
|
|
|
|
The logic corresponds to that for the keyboard language [`nomatch`](/developer/language/reference/nomatch) rule.
