Hi.
In "Trim" command we can extend or cut if we press the key "Shift".
However if we are using the "Length" command (parameter: Increment (delta)), Shift key is not available so we can type -0.50 meters or 0.50 meters if we want to add or reduce the length.
If would be interesting that "Length"--Increase would be compatible with "Shift" key.
Thanks.
