When you're watching a video or listening to music in VideoLAN's VLC media player, you can use the software hotkeys to skip forward and backward in the movie or song. Use one of these pre-defined key combinations to quickly skim through a media file and find the section that you want to listen to or watch. If you want to change the amount of time that VLC uses to define any of these skips, change the "Jump Sizes" settings in the program's options.
Launch VLC. Click "Tools" in the top menu bar, then click "Preferences" to open VLC's preferences section.
Click the radio button next to "All" in the lower left-hand corner to display VLC's "Advanced settings" section. Click the arrow next to "Interfaces" in the left-hand column, and then click "Hotkeys settings."
Click the text box next to the jump size you want to change in the "Jump sizes" section. Type the length of time, in seconds, that you want to set as the skip length. Repeat the process for all of the skip lengths that you want to change.
Click "Save" to apply the new skip times, and close the "Preferences" window.
Hold "Shift" for a very short skip, "Alt" for a short skip, "Ctrl" for a medium skip or "Ctrl" and "Alt" for a long skip. Then press the left or right arrow key to skip backward or forward, respectively.
