VolUp+Home+Power. If you get the stock recovery, you didn't install TWRP. (If this is an AT&T or Verizon Note 3, use Safestrap, not TWRP. You can't install TWRP (locked bootloader), so Safestrap inserts itself into the boot chain and lets you choose a normal boot or a Safestrap boot - which is a modified TWRP. (It looks and works like TWRP, but it runs on Samsung phones with locked bootloaders.) 3.72 for 4.3, 3,75 for 4.4.2, downgrade to 4.4.2 if you're at 4.4.4, install Safestrap, then replace the 4.4.4 bootloader (Odin the BL file) and boot to 4.4.4. Replace the bootloader with the 4.4.2 BL file and you boot to Safestrap, do what you have to do, then replace the 4.4.4 BL file to run the phone. (It's a pain, but Hashcode is too busy with the Ara project to rewrite Safestrap for later versions, and it looks as if no one is picking up the reins [or he's not relinquishing the source code]).
