  YouTube keyboard shortcuts

Play and pause a video

Press the spacebar or the 'k' key on your keyboard to play and pause a video.

Jump to start of a video

Pressing the 0 (zero) key on your keyboard will jump to the beginning of a video. The home key also works for jumping to the start of a video.

Jump to the end of a video or go to the next video

Pressing the end key on your keyboard will go to the end of the video. If you are playing a playlist, it goes to the next video in the playlist.

Skip or jump in the video

Fast forward or rewind

If you want to fast forward or rewind in increments of five seconds, press the left or right arrow keys. If you need to jump more than five seconds, hold down the Ctrl key and press the arrow key for the direction you want to jump in ten second increments.

Skip to video sections

Pressing the number keys from 1 to 9 seeks (jumps) to that percentage of the video. In other words, 1 jumps to 10%, 2 jumps to 20%, 3 jumps to 30%, etc.

Make the video full-screen

Pressing 'f' on the keyboard switches between full-screen and normal mode.

Tip

Pressing Esc also exits full-screen mode.

Turn up and down the volume

Pressing the up or down arrow keys turns up and down the volume of the video. If you are turning down the volume and continue to hold the down arrow key, it will eventually mute the volume.

Tip

Pressing 'm' on the keyboard also mutes and unmutes the volume.

 Remove formatting in Word from any pasted   text

When copying text from another document or Internet web page and pasting it into Microsoft Word, Word will keep the formatting of the text. For example, if you were to copy the text on this page to a Word file, this text would remain bold, and this text would remain blue. To remove the formatting in Microsoft Word from any text highlight the text and press the shortcut key Ctrl+Spacebar. The shortcut sets the text to the default font, removes the formatting, and even removes links.

Alternatively, you can use the Paste Special option or Keep Text Only option in Microsoft Word to paste the text with no formatting.

Bonus Tip: In most versions of Windows Ctrl+Windows Key + V also pastes text as plain text.

 Find files by date modified in Windows

Using the date modified feature in Windows File Explorer allows you to find any files that have been modified on a specific date or over a range of dates. Using this tip can be helpful for anyone who had lost a file, but knows when they last modified it.

How to find the date of modified files

1. Press the Windows key+E on the keyboard to open File Explorer.
2. On the left side scrolling menu, select the drive or folder in which you'd like to view dates (1).

3. Then, on the right side of the screen, type datemodified: (make sure to include the colon) into the search box (2).
4. You should see a menu appear that is similar to the one shown below.

5. From here, you have a few options:

• View a single day - Navigate to the day you're interested in and click it.
• View a range within a month - Click and hold down your left mouse button on the starting date, and then drag your mouse cursor to the ending date.
• View a range over a long period - If you need information that spans more than one month or year, you utilize a specific format in the search box. As an example, if you'd like to view the modified dates between October 13, 2018, and November 10, 2018, you would type: datemodified:‎10/31/‎2018 .. ‎11/10/‎2018 exactly as it is written there, and then press Enter.
