Tablet ctrl key alternatives?

[cassant]

How do I use shift, alt, etc. in Moho when using a tablet?
Little Green Dog video #3 describes using the shift key to switch to a lasso tool and select points, and using alt/opt to deselect points.
I can't see how to do this.
I'm new to Moho, using a Huion tablet and Mac.
I extended the desktop and shoved Moho's display over to the tablet, so I can see learning material on the laptop screen.
But moving the mouse back and forth is cumbersome, so I'm watching learning videos on an iPad, and just working with the tablet & drawing pen.
Selecting control keys on the laptop while trying to work on the tablet doesn't seem to work.
Is there some button combo on the tablet which needs to be set up somehow as an equivalent to shift, etc. ?
TIA for any pointers.

Some tablets have buttons on the bezel that you can program to behave like keyboard modifiers. I used to do this with older Wacom tablets, but I don't have buttons on my current Cintiq. Apart from using an actual keyboard, Wacom offers a portable button remote as an option. The Wacom remote works well enough but, unfortunately, it only works with Wacom tablets.

Lucikly, for other display tablets I've used, I found similar remote devices.

An inexpensive remote is the Huion Keydial (around $50). It looks like a numerical keypad and has a dial at the top with a button. The current model uses bluetooth, so I can place it anywhere near the tablet. I thought this device worked well, except the keys are unmarked and I had to remember what each 'blank' key did. To help me, I stuck my own labels on the keys that I printed with my Brother label maker. (I put labels on everything around here.)

One nice thing about this remote is that it's universal: unlike the Wacom remote, the Huion works with any tablet, including Wacom.

When I got a Microsoft Surface Laptop Studio tablet computer, I ran into a new problem: when the Surface is in tablet mode, the keyboard is inaccessible. Also, the Surface Pen has only one side-button, not two side-buttons like a Wacom pen, so I needed an alternative for simulating a Middle Mouse Button click.

The Huion Keydial worked well for me on the Surface, too, but I decided to upgrade my remote to the XENCELABS Quick Keys. Functionally, the Quick Keys does the same thing but what's cool about this device is the LCD panel with button labels that change when you change programs. This device can be used horizontally or vertically. No Bluetooth but it comes with a wireless dongle. I would have preferred it had Bluetooth, but to be honest, I plug in this remote with a USB cable most of the time to keep is charged. The remote costs quite a bit more ($99) than the Keydial, but I think it's worth it. The build is more solid (It's metal vs Huion's plastic,) and the LCD panel makes it much easier to use. Oh, and like the Huion, it works with any tablet.

BTW, I noticed that XP Pen makes the XP Mini Keydial, which is similar to the Huion's Keydial Mini but laid out horizontally like Xenscelabs Quick Keys. The XP Mini Keydial is more like Huion's Keydial (plastic, no LCD panel,) and costs about the same ($50). I'm assuming this is another universal device that works with any tablet. I don't have any experience with this one so be sure to check reviews from actual users.

Finally...

What I REALLY use MOST of the time with my Surface tablet when it's in tablet mode is a portable wireless keyboard called the Logitech MX Keys Mini. This tiny keyboard is SOLID gear, mostly metal and very durable. No number pad but it has all the essentials, long battery life, and it lights up too. It's small and has a low-profile, so it hardly takes up space in my backpack. Also, it takes up little desk space when I place it in front of my Surface in tablet mode, which is why I don't use the remote very much these days.

It might seem redundant to use this keyboard with the Surface Laptop because the tablet has a built-in keyboard, but it's very convenient when the Surface is in tablet mode. Better than using the on-screen keyboard, which can take up half the screen. (Since I got this keyboard, I wonder if I would have been just as happy with a regular 'non-laptop' Surface tablet.)

I also have a portable stand that angles the device to make it easier to draw on. It's like having a mini-Cintiq setup when I'm working away from home. The stand I use is the Parblo PR 100 Drawing Tablet Stand, another solidly built device that I highly recommend. (I learned about it from another tablet computer artist.)

Besides all this gear, I should point out that there are alternative ways to access Tools, Commands, and Navigation controls in Moho...and some of them are kinda hidden. I'll try to follow up later with information, but I really need to get back to working on tutorials right now.

Hope this helps!

Wow, thank you very much for this quick and detailed reply!
The man himself, your videos are enjoyable and clear.
You've opened my eyes to more options.
Keeping this reply short but I will look at all the gear you mentioned.
