The cancel key on a keyboard is typically a key found to the right of the backspace key and marked as “Cancel” or “Break”. It can typically also be identified by its keycode, which is usually Esc or F24 on PC keyboards.
In some cases, the cancel key might be shared with the pause button. This key is usually used to interrupt a running process and return control to the user. It can also be used to stop the current operation when entering or editing data.
In some programs, the cancel key might also be used as a way of exiting the program.
Which key cancels the changes?
The key that will cancel any changes you have made depends on the application you are using. In many programs, you can usually press the ESC (Escape) key to cancel the changes to your current action, such as when you are typing or editing text.
Additionally, in most programs you can press CTRL+Z (or CMD+Z on a Mac) to undo the last action, or CTRL+SHIFT+Z (or CMD+SHIFT+Z on a mac) to repeat a prior action. If those keys do not work, it may be helpful to look within the application itself for additional command shortcuts that could cancel changes.
Which key on the keyboard can cancel the active window?
The key on the keyboard to cancel the active window is the ‘Escape’ or ‘Esc’ key, located close to the top-right corner of your keyboard usually in the same area as the Function keys. This key can be used to close the active window or cancel an action (such as a delete operation).
Pressing the Escape key will bring up a dialog box to confirm the action you’d like to take. In some cases it will close the active window without confirming a dialog, while at other times you’ll need to press Escape a second time to confirm the action.
How do you press Cancel on a laptop?

Why Ctrl C is not working?
Ctrl+C (also known as “SIGINT”) is a keyboard shortcut most commonly used to interrupt or terminate a currently running process. If Ctrl+C is not working, it is likely because the process is programmed to ignore the signal.
This could be because the process is running in the background and does not require input from the user, or because the user does not have the required privileges to use the signal.
In addition, some processes have their own methods of interruption that override a Ctrl+C signal. In addition, some anti-virus software will prevent the signal from working, because it is seen as a security risk.
If Ctrl+C is still not working, it is possible that an error may have occurred within the operating system. If this is the case, it is recommended to restart the computer in order to flush any potential errors.

Pressing Alt + F4 (sometimes called an “Accelerator Key”) closes the active program or window you are in. It is the same as clicking the “X” button in the upper right corner of the window or selecting “Close” from the File menu.

You should also be aware that pressing Alt + F4 may not prompt you to save any changes you have made before the window closes.
