  2. Modifier key - Wikipedia

    en.wikipedia.org/wiki/Modifier_key

    For example, in most keyboard layouts the Shift key combination ⇧ Shift+A will produce a capital letter "A" instead of the default lower-case letter "a" (unless in Caps Lock or Shift lock mode). A combination of Alt+F4 in Microsoft Windows will trigger the shortcut for closing the active window; in this instance, Alt is the modifier key.

  3. Arrow keys - Wikipedia

    en.wikipedia.org/wiki/Arrow_keys

    At the Applesoft BASIC prompt, using the right and left arrow keys to move the cursor would add/remove characters the cursor passed over to/from the input buffer. Pressing the Esc key entered a mode where pressing the I, J, K or M keys would move the cursor without altering the input buffer. After exiting this mode by pressing Escape again ...

  4. Scroll Lock - Wikipedia

    en.wikipedia.org/wiki/Scroll_Lock

    In its original design, Scroll Lock was intended to modify the behavior of the arrow keys. When the Scroll Lock mode is on, the arrow keys scroll the contents of a text window instead of moving the cursor. [1] [2] In this usage, Scroll Lock is a toggling lock key like Num Lock or Caps Lock, which have a state that persists after the key is ...

  8. Linear-feedback shift register - Wikipedia

    en.wikipedia.org/wiki/Linear-feedback_shift_register

    In computing, a linear-feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state. The most commonly used linear function of single bits is exclusive-or (XOR). Thus, an LFSR is most often a shift register whose input bit is driven by the XOR of some bits of the overall shift register value.
