the hotkey for mesh select mode (vertex, edge, face) while in edit mode (ctrl + tab) has been reassigned in 2.8. Is there another hotkey assigned for this?
Blender 2.80 is taking a minimal shortcut approach, that is, it is removing many existing shortcuts in the default setup.
The idea is that we have a huge number of shortcuts assigned to tasks that even long terms blender users do not know about, some tasks even have multiple key combinations assigned to them, for example you can open a file with ⎈ CtrlO or you can press F1.
You can either start with this minimal setup and add shortcuts that make sense to you, which is now easier as there are less keys with tasks pre-assigned, or you can go back to the old 2.7x shortcuts.
When you start blender you can choose which keymap to use in the splash screen.
You can also change the keymap in the preferences.
Once you choose a keymap to use, you can save your settings so that it is used each time you start blender.
I am also using a laptop with "Emulate Numpad" turned on. Adding the "Alt" modifier to 1, 2, and 3 did not do anything. I discovered that I needed to remap the numbers themselves:
- Click the field with the number "1" in it.
- Press the "1" key on your keyboard.
Because you have "Emulate Numpad" turned on, you will see it change to "Numpad1":
You can use ctrl+1/2/3 for vertex select, edge select, face select and shift+1/2/3 to add more than one selection mode
