You generally can’t take apart the touchpad, but you may be able to replace it.
Adding a USB mouse will not override the touchpad. If you wanted to, you could reassign the buttons if it makes things easier (since you use left button far more often, might want to switch it with right).
Plus, I think most touchpads will do a ‘left click’ if you tap the touchpad in the centre sharply.
I should have explained, I do tap the pad as a “left click” as much as possible. But I’ve never got the knack of using that for certain things, like clicking and dragging to highlight text. So my idea is to use the mouse as little as possible, but have it ready for those times I need it.
Am I the only one who can’t use a touchpad at all ? Perhaps I’m clumsy or heavy-handed, but the cursor jumps hither and yon, the slightest touch is interpreted as left click. (Or maybe I need to change some sensitivity setting I’m unaware of?)
Actually, I’d suggest turning off tap to click. The settings should be under Mouse in Control Panel on Windows, or Keyboard and Mouse under System Preferences on a Mac. Sensitivity should be in there, too.
Maybe it’s just me, but I consider the touchpad as a last resort when there’s no mouse available. I can’t imagine anyone preferring the touchpad. It’s also a major pain when I’m trying to type on a laptop keyboard, because if I accidentally touch the keypad as I’m typing, the cursor will jump up or down to a completely different place in the document than where I was typing.
Give me an external keyboard and mouse with my laptop any day.
My Toshiba works with both mouse and touchpad, wife’s Advent disables touchpad when mouse is plugged in (same OS - Ubuntu.)
Some touchpads are very configurable and can emulate ‘sticky keys’
However, for use in bed a trackball might be worth considering as a better alternative. My son will not be parted from his, similar to this one
Not that I’m trying to talk you into doing it, but the usual gesture for click-and-hold is double-tap-and-hold. Tap once, then tap again holding down the second time, then when you move it performs a drag.
