The wiki help says:
https://help.libreoffice.org/Common/Copying_Attributes_With_the_Format_Paintbrush
> By default only the character formatting is copied ; to include paragraph 
formatting, hold down Ctrl when you click. To copy only the paragraph formatting,
 hold down Ctrl+Shift when you click.

This is a feature, done by the following commit:

  Format paintbrush default behaviour
  Don't copy paragraph formats by default

I believe this feature is useful. But there are many many users who are not aware of this feature. When they want to format there paragraph and text with paintbrush, they click on the paintbrush icon, select the paragraph or text they want to apply the format, and wait, and finally don't get what they need. (See the many duplicates to bug 59029.)

Thus I am requesting to add a tooltip to this feature for CTRL and CTRL+SHIFT usage.

Steps to reproduce:

1. Select paragraph A.
2. Click the paintbrush toolbar icon.
3. Move your mouse to over the target paragraph/text you want to apply format for.
---> At step 3, a “Paint Bucket” will appear which indicates that you are ready to select the text.

The enhancement request is: 
Show a tooltip box next to the “Paint Bucket”, to tell the user how to apply format for "chars only", "chars and paragraph", and "paragraph only" by holding CTRL and CTRL+SHIFT.
