This should do the trick:

%create part of your data structure as an example
EEG=struct;
EEG.event(1).type='11';EEG.event(1).latency=rand;
EEG.event(2).type='keypad1';EEG.event(2).latency=rand;
EEG.event(3).type='21';EEG.event(3).latency=rand;
EEG.event(4).type='31';EEG.event(4).latency=rand;
EEG.event(5).type='keypad1';EEG.event(5).latency=rand;

L=ismember({EEG.event.type},{'keypad1'});
[EEG.event(L).type]=deal('1');
