+			One of the eariest accounts can be found in the article <a
+			href="https://doi.org/10.1016/S1474-6670(17)64475-6">Statistical
+			Distribution of Arabic Letters Aids to the Design of a New
+			Keyboard</a> by Al-Ramly et al published in 1980.
+			<!-- -->
+			The Arabic half of the proposed bi-lingual layout seems to be
+			hand-optimized based on several metrics including character
+			frequencies – without mentioning a source for them though – visual
+			similarity (“letter groups”) and their position on previous
+			layouts.
+			<!-- -->
+			It tries to balance load between hands, assign more work to index
+			and middle fingers and place common letters in the home row.
+			<!-- -->
+			However the asymmetry given in the article, 0.032, cannot be
+			reproduced here.
+			<!-- -->
+			For the most part the layout lacks combining and pre-combined
+			characters, a task that is left to “machine intelligence” making it
+			hard to use nowadays.
+			</p>
+			<p>
+			While the layout distributes load between fingers quite well it
+			favors the left hand by assigning <bdo dir="ltr" lang="ar">ا</bdo>
+			and <bdo dir="ltr" lang="ar">ل</bdo> to it.
+			<!-- -->
+			The decision to place <bdo dir="ltr" lang="ar">ث</bdo> in a very
+			prominent spot seems weird, given it only accounts for 0.5% of all
+			symbols, even in their own analysis.

+			<p>
+			Another article from the early days of computers published in 1990
+			is <a
+			href="https://archive.org/details/computers_and_the_arabic_language_1990/page/n112/mode/2up">Design
+			of Arabic Keyboard Layout Based on Statistical Properties of Arabic
+			Characters</a> by Idlebi et al.
+			<!-- -->
+			They present two examples of programmatically optimized layouts and
+			account for character and bigram frequencies based on a corpus of
+			100.000 characters, finger movement time of unknown origin and finger
+			load.
+			</p>
+			<p>
+			Unfortunately the results use 12 keys per row and are not suitable
+			for use with current European keyboards, which usually feature only 11 keys
+			in the bottom row.
+			<!-- -->
+			Thus the layout displayed below lacks the Arabic question mark and
+			comma in the bottom right.
+			<!-- -->
+			Probably due to their unusual assumption that middle- and
+			ring-finger rest in the top row their results are suboptimal,
+			placing both <bdo dir="ltr" lang="ar">ا</bdo> and <bdo dir="ltr"
+			lang="ar">ي</bdo> in the top row.
+			<!-- -->
+			Their analysis notices this and suggests improved positions for
+			both characters, but these are not actually implemented.
+			<!-- -->
+			The big asymmetry is caused by placing <bdo dir="ltr" lang="ar">ا
+			ل ي</bdo> and <bdo dir="ltr" lang="ar">و</bdo>, four of the five
+			most frequent letters, on the right hand side.
