In ms-office-word shortcut-key for special characters can be applied as following:
But now I am using Libre-office Which is pre-installed with Ubuntu! and want to put shortcut-key for special characters. But there is not such option available:
It is difficult for me to write every-time with Unicode Ctrl+Uthen055thenEnter(0055 is only example for U which is not special-character).
Thus, Help me to add shortcut-key or any other method as I am leaving ms-office and working with libre-office Version: 4.2.3.3 (open-source and pre-installed with Ubuntu 14.04)
