While inputting data into the FMS; each key stroke would often cause multiple digits to populate the scratch pad. When entering the fuel weight into the ACARS for the Track Detail Message (TDM); I input 1;100 instead of 11;000. We didn't receive any error message and don't notice it. We set the speeds according to the TDM. We took off from ATL with takeoff data that was 10;000 pounds too low. I realized it when I pulled up our landing data and our fuel on arrival was -3;000 pounds.We didn't encounter any low speed indications; probably because the N1 setting was higher than the N1 required in the TDM. However; taking off with speeds predicated on erroneous takeoff weight was unsafe and could have resulted in an undesired aircraft state.Fix the FMS anomaly that causes multiple characters per key stroke. Program safeties for the fuel amount; similar to those that exist for the number of passengers in each zone; so that the ACARS wouldn't accept a planned fuel that would result in landing with unreasonable amounts of fuel. By the way; we received landing data included -3;000 pounds of estimated fuel on arrival; and the aircraft landing weight was stated as Zero Fuel Weight (ZFW) minus 3;000 pounds.
CL600 FO reported taking off with a data error of 10;000 LBS entered into the FMS. FMS multiple character input issue was a factor in the incident.
