If you have an old smart TV in your house, then you will see red, yellow, green and blue buttons along with other buttons on its remote. Some set-top boxes also have such buttons on their remotes.

Let us tell you that these buttons are context-shortcut sensitive, about which most people are not aware. Today we will tell what is the function of these colorful buttons on the remote.

Started before the advent of internet

Giving red, yellow, green and blue buttons on the remote started before the Internet. Actually, these buttons were started for teletext. Before the advent of the Internet, it was an information service in Europe and the UK. In this, colour-coded links were shown at the bottom of the screen. By pressing the button of the color of which the link was there, the user could click on those links, which would take him to the page related to weather or news etc. Now this service has been stopped, but TV companies have not stopped providing these buttons and now they are being used for navigation.

Even today, these colorful buttons are seen on the TV remotes of many companies. These work as shortcuts or hot keys. That means some function is added to these buttons. In such a situation, as soon as you press this button, that function will open. Many companies also provide the option to customize these buttons, where users can customize them as per their wish.
