24.5. Key names

The detail part of an event pattern for a KeyPress or KeyRelease event specifies which key you're binding. (See the Any modifier, above, if you want to get all keypresses or key releases).

The table below shows several different ways to name keys. See Section 24.6, “Writing your handler”, below, for more information on Event objects, whose attributes will describe keys in these same ways.

The .keysym column shows the “key symbol”, a string name for the key. This corresponds to the .keysym attribute of the Event object.
The .keycode column is the “key code.” This identifies which key was pressed, but the code does not reflect the state of various modifiers like the shift and control keys and the NumLock key. So, for example, both a and A have the same key code.
The .keysym_num column shows a numeric code equivalent to the key symbol. Unlike .keycode, these codes are different for different modifiers. For example, the digit 2 on the numeric keypad (key symbol KP_2) and the down arrow on the numeric keypad (key symbol KP_Down) have the same key code (88), but different .keysym_num values (65433 and 65458, respectively).
The “Key” column shows the text you will usually find on the physical key, such as tab.

There are many more key names for international character sets. This table shows only the “Latin-1” set for the usual USA-type 101-key keyboard.
