select and delete are common editing terms. if you compare any of your posts with any other post you'll note that you have an edit button on yours. but you've discovered that. when you click the edit button, you get your post back in an edit box. by placing the flashing cursor anywhere in the edit box with your mouse (click the left mouse button to fix the insertion point) you can then insert additional text at that point, or you can delete text at that point (using the delete or backspace keys).
you can also use the mouse to select a whole string of text. this is done by holding down the left mouse button while dragging it (the mouse, that is) across the text you want to highlite (select). think of using a yellow marker in a book. when you have some text selected in this manner, you can type to replace it or just use the delete key to remove it.
