It is due to above reasons and many more that I recommend it. All these features indeed help me in faster development, but there is another method that I use for faster development and that is Keyboard Shortcuts. I am a huge user of Keyboard shortcuts and use them not just in Notepad++ but in even other software/applications.
Here is the list of all the keyboard shortcuts as mentioned in the Notepad++ Documentation. I will mark some of the shortcuts, in bold, that I use most frequently. All the shortcuts can be changed from the Shortcut Mapper which can be opened from Settings > Shortcut Mapper Menu.
