And I'll throw in... use 'regular' accelerator keys for the controls,
Alt/I for Ignore button
Alt/A for Add to dictionary button
Alt/C for Change Selected Word to: combo/list box,
Alt/F for Filter text box
Alt/S to toggle Show All Words checkbox
Alt/E to toggle Case-insensitive Sort checkbox
Alt/R for Refresh button
Maybe - Alt/K for OK ??
Maybe - Alt/W for last position in word list ??
