Note: This is a personal opinion of the reader to use the following commands/tools. Even if you don't prefer to use them explicitly, you should know that these tools/commands exist, so even if you don't execute the commands, just go through them.
Yes, the name is self-explanatory. Keyboard remapping is just remapping the functionality of keys of your keyboard. So, if you want your shift key to act as ctrl key, you can do this with keyboard remapping( Remember, remapping shift to ctrl won’t automatically remap ctrl to shift. You need to do that explicitly, like you did with the other.)
We have demonstrated how NVIM and VIM are better editors than traditional ones. You may have noticed that we are required to use the esc key multiple times. So you can remap esc key to some other key you use less often( it’s the Caps Lock key in my case, lol).
Keys or Shortcut, which ever you want to change. Select the keys and complete the changes.feh is a lightweight image viewer for the command line. Imagine you are accessing a server, and you find a piece of data which is an image. How will you open it from the command line? The server won’t have such application to open the image and nor can you copy the data everytime to your computer to view it. So a lightweight image viewer like feh is of great help in such cases.
You can install the latest release using
brew install feh
Or, if you are fine with an older version, use apt.( Why does apt usually have older versions? Check out the heading “How NOT to install NVIM” from here)
sudo apt install feh
Use the following command to open any image on command line
feh <address_of_image>
Replace <address_of_image> with actual address of the image. If in the same directory directly use the image name.
