Important Tips of Text Editors

Within the vim tutorial in my Ubuntu Linux, I find many amazing things. First, the cursor’s movement is very interesting as H, J, K, and L have the same functions as keyboard arrows. Using the letter keys is faster than arrows, but one needs more practice to be familiar with them. Second, a letter “i” is very important because it is the way to insert text. Third, a letter “a” is also very important because it is the way to append text. Last, a letter “x” is also very important because it is the way to delete a text. After practicing in the text editor, I configured files such as “.bashrc” and “/etc/apt/sources.list”. After configuring those files, there are many results such as hidden files in the first one and unaccess files in the second one. In the second configuration, you can access those files by deleting the pound sign.
