Hoofdletterwijziging

Leren

De hoofdletter van een letter is gewijzigd van hoofdletter naar kleine letter of omgekeerd.

Case flip errors occur when the Caps Lock key is accidentally engaged or the Shift key is pressed/released at the wrong time. This changes a letter from uppercase to lowercase or vice versa. While the letter identity remains correct, the case change can cause issues in case-sensitive systems.

Uppercase letter becomes lowercase (A→a) or lowercase becomes uppercase (a→A)

• HELLO → HeLLO (E became lowercase)
• AB-1234 → Ab-1234 (B became lowercase)
• CODE → COdE (D became lowercase)
