In the "Update PCB from schematic" tool in version 7, IIRC you just have
to *not* select "Re-link footprints to schematic symbols based on their
reference designators". If that doesn't work, you can also go around
all the components on the PCB manually giving each one the correct
designation, and then update the PCB with that box *selected*. I know
the latter works, because I partially did this last week (for completely
different reasons).

Robert

You don't want to get me started about <users> making backups of anything valuable, do you?? ;-)? I think we've had that conversation before.

Unfortunately, the backup I need is corrupted (KiCad apology message received) , due to having KiCad running while some other updates were going on. It looks like I have to start all over again.

Fortunately, KiCad saves backups. Look in your PCB project directory. You should have a folder of zips called "<Project_name>-backups".

In KiCad 7 and 8, they are at C:\Users\[user]\AppData\Roaming\kicad\X.0\user.hotkeys, but the texts are barely readable by humans.

For the hotkeys, find where the KiCad configuration files are stored. I guess on Windows, it would be somewhere close to:

Thanks, Tony. I will investigate. It would be good to put those locations in the Manual.

I have another question: is there a way of printing the list of keyboard shortcuts? Since it is an HTML page in the on-line manual, I can't see how to do it.

It's 'Update the PCB from schematic' that causes the problem.? V8 seems quite a bit different from v6, and better, but driving lessons are required.

You should be able to 'feed forward' the changes. That should then renumber the component placements. I can't remember the appropriate commands at the moment, and I also haven't got around to playing with v8 yet (but hope to do so soon).

Yes, it does work, but 'Place all units' doesn't work. I had to find a work-around to get both poles into the schematic.

SW_DP3T looks something like what you are asking form it's in the switch
lib.

Get used to making your own footprints and symbols it's one of the most
useful things you can do as it's a great time saver.

The way to go is find a symbol (or footprint) that's close, copy it,
rename and save in your own libs which you should be doing anyway, and
it's not a good idea to use the provided libs directly as you have no way
of knowing if an update has changed something. It's should not, bit it
can happen.

But I can't find? a schematic symbol for it, only SPDT_MSM for a 
single-pole version. Do I have to make a new symbol for it? That means 
delving into the 'user libraries' process, which I find very confusing.

Actually, I am using only one pole, but that switch fits mechanically 
very well and I have a supply.

Thanks, Andy. Yes, that's what I should be doing, but it's a big job to get started on. I'm trying to appease the alligators, before draining he swamp.

Yes, that was the problem, but the designations need to show in order to put the components in their places.

I agree that this just sounds like the layers are switched off

usually on the right hand side of the window there is a panel with some
tabs Layers Objects Nets 

Select layers and make sure there is an eye symbol and not a stop symbol.

It's quite common to turn off the silkscreen and other layers as they can
cause a lot of mess on screen when you are trying to lay out a board.

You can place a PWR_FLAG symbol on the relevant net. You can find this in symbol folder called "Power". Usually, GND also needs one.
