To copy text on a computer, you can use either the mouse or keyboard shortcuts: Using Keyboard Shortcuts (on Windows PC):

• Highlight the text you want to copy by clicking and dragging the mouse over it.
• Hold down the "Ctrl" key and press the "C" key at the same time to copy the text.
• To paste the copied text elsewhere, place the cursor where you want to paste, hold down "Ctrl," and press "V."

Additional shortcuts:

• "Ctrl" + "A" to select all text in a document or field.
• "Ctrl" + "X" to cut selected text (removes it and copies it to clipboard).

Using Mouse:

• Highlight the text by clicking and dragging over it.
• Right-click the selected text and choose "Copy" from the context menu.
• Right-click where you want to paste and choose "Paste."

These actions work in most applications, including web browsers, word processors, and email clients.
