The characters ², ³, {, [, ], }, \, @, |, µ, ~, and € are accessed by holding the AltGr key and tapping the other key. The Alt key on the left will not access these additional characters. Alternatively Strg+Alt and pressing the respective key also produce the alternative characters in many environments, in order to support keyboards that only have one left Alt key.[2]

The accent keys ^, ´, ` are dead keys: press and release an accent key, then press a letter key to produce accented characters (ô, á, ù, etc.; the current DIN 2137-1:2012-06 extends this for e.g. ń, ś etc.). If the entered combination is not encoded in Unicode by a single code point (precomposed character), most current implementations cause the display of a free-standing (spacing) version of the accent followed by the unaccented base letter. For users with insufficient typing skills this behaviour (which is explicitly not compliant with the current DIN 2137-1:2012-06) leads to mistype a spacing accent instead of an apostrophe (e.g., it´s instead of correctly it's).[3]

Note that the semicolon and colon are accessed by using the ⇧ Shift key.

The "T1" layout lacks some important characters like the German-style quotation marks („“ and ‚‘). As a consequence, these are seldom used in internet communication and usually replaced by " and '.

The "T2" layout newly defined in DIN 2137-1:2012-06 was designed to overcome such restrictions, but firstly to enable typing of other languages written in the Latin script. Therefore, it contains several additional diacritical marks and punctuation characters, including the full set of German, English, and French-style quotation marks in addition to the typographic apostrophe, the prime, the double prime, and the ʻokina.

The image shows characters to be entered using AltGr in the lower left corner of each key depiction (characters not contained in the "T1" layout are marked red). Diacritical marks are marked by a flat rectangle which also indicates the position of the diacritical mark relative to the base letter.

The characters shown at the right border of a keytop are accessed by first pressing a dead key sequence of AltGr plus the × multiplication sign. This X-like symbol may be thought of as an "extra" dead key or "extra" accent type, used to access "miscellaneous" letters that do not have a specific accent type like diaeresis or circumflex. Symbols on the right border shown in green have both upper-case and lower-case forms; the corresponding capital letter is available by pressing the Shift key simultaneously with the symbol key. For instance, to type the lower-case æ ligature, hold the AltGr key and type ×, then release both keys and type the (unshifted) A key. To type the upper-case Æ ligature, hold the AltGr key and type ×, then release both keys, hold Shift and type the (shifted) A key. An active Caps Lock can be used instead of the Shift key to obtain the Æ ligature and similar letters.

In addition, DIN 2137-1:2012-06 defines a layout "T3", which is a superset of "T2" incorporating the whole "secondary group" as defined in ISO/IEC 9995-3:2010. Thus, it enables to write several minority languages (e.g. Sami) and transliterations, but is more difficult to comprehend than the "T2" layout, and therefore not expected to be accepted by a broad audience beyond experts who need this functionality.
