Let's accept it, sometimes when we write a lot of code faster, we usually press combinations of keys in the wrong way, which leads to unexpected behaviour in the IDE. In this case, for netbeans, a lot of users with the same problem that i have, tend to enable the rectangular selection feature.
This feature allows the user to select some content of the editor with a rectangular shape, instead of selecting entire lines. The most common use case, is when you copy a snippet from a website that provides you with a piece of code that contains the number of the lines as well, for example:
As you can see, we can easily get rid of this with the rectangular selection, just selecting the numbers and deleting them. If just like me, you discovered this feature by accident, and probably don't want to use in this moment, you can enable/disable it easily.
To disable/enable the rectangular selection just search for the Toggle Rectangular Selection button on the toolbar under the opened files:
Simply clicking on this icon will toggle this feature.
Toggle with Keyboard Shortcuts
If you like to use shortcuts instead, the following combinations on these platforms should do the trick:
- On Windows and Linux: Ctrl + Shift + R
- On Mac: Shift + Meta + R or Shift + Command + R
Happy coding !
