I learned to run Excel ( and 123 before it) in the old days when almost everything could be done from the keyboard. Essentially just type the first letter of an item in a menu and then the first letter of an item in the first submenu, etc. Much, much, much faster.
I have recreated that capability in KM to delete a highlighted block (~db), delete the column of a highlighted cell (~dc), delete the row of a highlighted cell (~dr), format the highlighted cells (~fe), format the column width of a highlighted cell (~fo) [the last two have the same first letter so had to use the second letter], insert a column at the cursor (~ic) and finally insert a row at the curson (~ir).
Has anybody gone down this row before? Happy to share thoughts.
