In LibreOffice Writer, we need to click menu every time we need to insert copyright symbol. How if we need to do it 20 times, for example? That will be not efficient in time. Actually, Writer provided AutoCorrect feature for some most common symbols such as copyright, trademark, and registered. To insert any, you just need to type some characters. You may insert it in any place in your document. You don't need to access the menu again.
Copyright
To insert copyright symbol, type
(C)
and tap space bar once. Notice the uppercased 'C' not lowercased 'c'. Otherwise it won't work.
Trademark
To insert trademark symbol, type
(tm)
and tap space bar once. Notice the lowercased 'tm', not uppercased 'TM'.
Registered
To insert registered symbol, type
(R)
and tap space bar once. Notice the uppercased 'R', not lowercased 'r'.
