It is possible to add explanations to certain expression or acronyms.
The example above shows the (in this case case-sensitive) expression OOB (you see it is "underdot'ed") with the explanation "out of the box" while pointing with the cursor on it.
Do you think this is a useful feature and if so what acronyms could/should be added to be automatically highlighted?

dtb - device tree blob
