DrScheme provides special Scheme-specific editing commands for
manipulating expressions:
Command Key Binding Move forward past an expression ESC-right or ESC-Ctl-F Move backward past an expression ESC-left or ESC-Ctl-B Select forward expression ESC-shift-right or ESC-Ctl-Shift-F Select backward expression ESC-shift-left or ESC-Ctl-Shift-B Move outside an expression ESC-up or ESC-Ctl-U Move inside an expression ESC-down or ESC-Ctl-D
See Stepping for information about using DrScheme's Stepper to step through expressions mechanically.
To write down step-by-step evaluations ``by hand,'' DrScheme's definitions window can be used as a plain text editor. The cut and paste functions, available from the menu or through the usual key bindings, make it easy to copy the expression from one step as a starting point for the next step. The keybindings described in the previous section are also useful.
