The supplied support-files/Dyalog-Keyboard/apl.xmodmap does not map the alt-shift-H to ⍙ as shown in ]keyb.
Interestingly, support-files/apl.xmodmap does. Why would they be different? The following patch corrects this for support-files/Dyalog-Keyboard/apl.xmodmap: *** apl.xmodmap~ 2014-08-05 15:39:45.334064143 -0500 --- apl.xmodmap 2014-08-06 08:20:04.987666617 -0500 *************** *** 33,39 **** keycode 40 = d D U230A keycode 41 = f F underscore keycode 42 = g G U2207 ! keycode 43 = h H U2206 keycode 44 = j J U2218 U2364 keycode 45 = k K apostrophe keycode 46 = l L U2395 U2337 --- 33,39 ---- keycode 40 = d D U230A keycode 41 = f F underscore keycode 42 = g G U2207 ! keycode 43 = h H U2206 U2359 keycode 44 = j J U2218 U2364 keycode 45 = k K apostrophe keycode 46 = l L U2395 U2337
