Using SelectTab command inserts a character into the terminal

I added the following bindings to the configuration file.
When switching between tabs, the numbers 1 and 2 are inserted respectively

```
[[keyboard.bindings]]
action = "SelectTab1"
key = "1"
mods = "Command"

[[keyboard.bindings]]
action = "SelectTab2"
key = "2"
mods = "Command"
```
