Many modifications can be done to Text. Some are available in Text Option Bar, but some aren't. Here is a little overview of the most useful options.
The Tool Controls Bar provides several options such as :
Ctrl +B and Ctrl + I applies bold and italic to the selected text.
Kerning : Alt with arrows left and right increases or decreases the space between characters at the end or beginning of the selection. You can also use Alt + <, Alt + > to decrease or increase the space after all characters in the selection. Pressing Shift will change the letter spacing more significantly. Use the menu of the menu if you are not satisfied with it.
Pressing Alt + [, Alt +] rotates precisely the letters; Ctrl + [, Ctrl + ] do 90° rotation at once.
