Adjusting keyboard delay timing in Sparky
From NMR Wiki
Sparky commands can be typed from the keyboard as combination of two keys. The software has special delay setting helping read those commands.
Any two keys typed within that period will be interpreted as a command. If more time elapses between two keys, then the first keystroke is 'forgotten' by software.
Default setting is 3 seconds which is probably too long.
'File'->'Preferences...' (or type pf)
Type a number about 0.7-1.0 seconds into 'Maximum time between accelerator keys (sec)' field.
Click 'Apply' or 'Ok' button.
