Deleting emails: Deleted emails do not go to the recycle bin. They go to the Deleted items folder.

Delete single emails by clicking the email, then tap the Delete key. Use Shift and Delete if you wish to delete the email permanently (to save you having to delete it again from the Deleted items folder).

To delete a block of emails.  Click the first email in the block then hold down the Shift key and click the last one in the block. The block will be selected (highlighted). Then use the Delete key or Shift and Delete.

To delete an entire email folder's contents: Click the first email then hold down the Ctrl key and tap the A key (A is for All). This will select all the emails ready for deleting in one go.

To delete a quantity of selected emails: Hold down the Ctrl key and click all the emails you wish to delete. This will select the chosen emails ready for deleting in one go.
Another method: The picture below shows a block of emails selected except for 3. The whole block was selected, then the 3 to be retained were de-selected by clicking them whilst holding down the Ctrl key. The Delete key would then delete only the selected items in blue.

NEVER delete a program file. Only delete files that you have created. If you want to delete a program from your computer you MUST use the Control Panel as follows:-
Click Start-->Control Panel. Make sure you are in Classic View not Category view.
Double click the Add or Remove Programs... icon. Wait while the list is populated.
Then, in the list of programs, click the program you wish to remove from your computer, click the Remove button and follow the screen instructions. You may have to restart the computer to finalise the removal.

The Del or Delete key deletes letters or spaces to the right.

Deleting blank lines: Click at the start of the blank line, then tap the Delete key.

Deleting a block of text, a word, or a line of text:
Select (highlight) the item to be deleted and then press the Delete key.

To delete any file (documents, photos, spreadsheets, music, but NOT programs) select the file (highlight it) and press the Delete key. This pops the file into the Recycle bin where it can be recovered if necessary.

Whoops! You just deleted a file or folder and now you need it. Double click the Recycle bin icon on the Desktop. You will see all your deleted files and folders listed in alphabetical order. Find the file you want to restore. Click it, then click the words Restore this item on the left hand panel, then click OK. Now the file will be back where it was before you deleted it.

Oh dear! You just deleted something in a document by accident. To restore the deleted item, click the Undo button  on the tool bar.

To delete a file or email permanently, instead of sending it to the Recycle bin (or the Deleted Items folder), select the file or email, then hold down the Shift key and tap the Delete key.

To delete a block of files or folders click the first one, then hold down the Shift key and click the last file or folder. Release the Shift key. This will select the block. Then tap the Delete key.

To delete a group of randomly selected files/folders. Click the first file or folder you wish to delete. Hold down the Ctrl key and click each file or folder you wish to delete. If you accidentally click the wrong file click it again to de-select it. Then release the Ctrl key and tap the Delete key.
