I typically add shortcuts like Alt-1 for "No grid" and Alt-2 for "the grid"
(0.05 mm in my case) to ~/.pcb/{g,}pcb-menu.res; in Lesstif GUI,
the layers are switched on and off with Ctrl-{1,2,3..}; I think you can
add the same for the silk layers, too (see the documentation on the actions).

PCB is customisable, and it becomes much more convenient when locally
customised.

BTW, I use thinline mode (`|' in default keybindings) with Ineiev's
"pedantic thinline" patch (assigned to Ctrl-[) to detect short and
merged lines.

I usually drag one of the line endpoints out of the pad (point with cursor
over the end, the cursor changes its form to a fancy square, then take
it and move away; the line ends are easier to see in thinline mode);
this does not work with vias, though.

Reasonable ideas (I really like the first one);
but you evidently forgot to attach your patches.

Best regards,
