My bash terminal starts with my own shortcuts and

     ^a         ^e       \
  <-------   -------->    } Moving
    alt-b    alt-f       /
     <----   --->       /
       ^b    ^f        /
         <- ->z 

$ cp monfi[c]hier dir/

     <----   --->
     ^w     alt-d       \
  <-------   -------->   } Erasing
     ^u         ^k      /

precisely because combinatorial mindset and efficient navigation are so important to my workflow.
