Ctrl-A does not work at Calcite tabs

[snuyanzin]

Is there a way to have key-stroke ctrl-a working at Calcite tab in the same way like it works at OQL tab?
Currently (ubuntu 19.04, MAT 1.8.1, mat-calcite-plugin 1.4.0) at calcite tab it does nothing

I just checked the behaviour in MAT 0.15-snapshot, and it looks like the root cause is a defect in OQL: https://bugs.eclipse.org/bugs/show_bug.cgi?id=582654
